+ check under socket_wrapper. The first is a missing 'break' before
+ the (heimdal specific) IPv6 support. The second works around the
+ fact that sendto() *may* object to a destination being specified.
+ It appears to be that on Linux, this objects (with EISCONN) for
+ unix stream sockets, but not for TCP sockets. The alternate fix
+ would be to have the KDC use 'send()' in this case. Andrew Bartlett.

+.Nm erealloc ,
+.Nm esetenv ,
+.Nm estrdup ,
+.Nm ewrite
+.Nd exit-on-failure wrapper functions
+.Sh LIBRARY
+The roken library (libroken, -lroken)
+.Sh SYNOPSIS
+.Fd #include <roken.h>
+.Ft "void *"
+.Fn ecalloc "size_t number" "size_t size"
+.Ft "void *"
+.Fn emalloc "size_t sz"
+.Ft ssize_t
+.Fn eread "int fd" "void *buf" "size_t nbytes"
+.Ft "void *"
+.Fn erealloc "void *ptr" "size_t sz"
+.Ft void
+.Fn esetenv "const char *var" "const char *val" "int rewrite"
+.Ft "char *"
+.Fn estrdup "const char *str"
+.Ft ssize_t
+.Fn ewrite "int fd" "const void *buf" "size_t nbytes"
+.Sh DESCRIPTION
+These functions do the same as the ones without the
+.Dq e
+prefix, but if there is an error they will print a message with
+.Xr errx 3 ,
+and exit. For
+.Nm eread
+and
+.Nm ewrite
+this is also true for partial data.
+.Pp
+This is useful in applications when there is no need for a more
+advanced failure mode.
+.Sh SEE ALSO

+.Sh NAME
+.Nm getarg ,
+.Nm arg_printusage
+.Nd collect command line options
+.Sh SYNOPSIS
+.In getarg.h
+.Ft int
+.Fn getarg "struct getargs *args" "size_t num_args" "int argc" "char **argv" "int *optind"
+.Ft void
+.Fn arg_printusage "struct getargs *args" "size_t num_args" "const char *progname" "const char *extra_string"
+.Sh DESCRIPTION
+.Fn getarg
+collects any command line options given to a program in an easily used way.
+.Fn arg_printusage
+pretty-prints the available options, with a short help text.
+.Pp
+.Fa args
+is the option specification to use, and it's an array of
+.Fa struct getargs
+elements.
+.Fa num_args
+is the size of
+.Fa args
+(in elements).
+.Fa argc
+and
+.Fa argv
+are the argument count and argument vector to extract option from.
+.Fa optind
+is a pointer to an integer where the index to the last processed
+argument is stored, it must be initialised to the first index (minus
+one) to process (normally 0) before the first call.
+.Pp
+.Fa arg_printusage
+take the same
+.Fa args
+and
+.Fa num_args
+as getarg;
+.Fa progname
+is the name of the program (to be used in the help text), and
+.Fa extra_string
+is a string to print after the actual options to indicate more
+arguments. The usefulness of this function is realised only be people
+who has used programs that has help strings that doesn't match what
+the code does.
+.Pp
+The
+.Fa getargs
+struct has the following elements.
+.Bd -literal
+struct getargs{
+ const char *long_name;
+ char short_name;
+ enum { arg_integer,
+ arg_string,
+ arg_flag,
+ arg_negative_flag,
+ arg_strings,
+ arg_double,
+ arg_collect
+ } type;
+ void *value;
+ const char *help;
+ const char *arg_help;
+};
+.Ed
+.Pp
+.Fa long_name
+is the long name of the option, it can be
+.Dv NULL ,
+if you don't want a long name.
+.Fa short_name
+is the characted to use as short option, it can be zero. If the option
+has a value the
+.Fa value
+field gets filled in with that value interpreted as specified by the
+.Fa type
+field.
+.Fa help
+is a longer help string for the option as a whole, if it's
+.Dv NULL
+the help text for the option is omitted (but it's still displayed in
+the synopsis).
+.Fa arg_help
+is a description of the argument, if
+.Dv NULL
+a default value will be used, depending on the type of the option:
+.Pp
+.Bl -hang -width arg_negative_flag
+.It arg_integer
+the argument is a signed integer, and
+.Fa value
+should point to an
+.Fa int .
+.It Fa arg_string
+the argument is a string, and
+.Fa value
+should point to a
+.Fa char* .
+.It Fa arg_flag
+the argument is a flag, and
+.Fa value
+should point to a
+.Fa int .
+It gets filled in with either zero or one, depending on how the option
+is given, the normal case being one. Note that if the option isn't
+given, the value isn't altered, so it should be initialised to some
+useful default.
+.It Fa arg_negative_flag
+this is the same as
+.Fa arg_flag
+but it reverses the meaning of the flag (a given short option clears
+the flag), and the synopsis of a long option is negated.
+.It Fa arg_strings
+the argument can be given multiple times, and the values are collected
+in an array;
+.Fa value
+should be a pointer to a
+.Fa struct getarg_strings
+structure, which holds a length and a string pointer.
+.It Fa arg_double
+argument is a double precision floating point value, and
+.Fa value
+should point to a
+.Fa double .
+.It Fa arg_collect
+allows more fine-grained control of the option parsing process.
+.Fa value
+should be a pointer to a
+.Fa getarg_collect_info
+structure:
+.Bd -literal
+typedef int (*getarg_collect_func)(int short_opt,
+ int argc,
+ char **argv,
+ int *optind,
+ int *optarg,
+ void *data);
+
+typedef struct getarg_collect_info {
+ getarg_collect_func func;
+ void *data;
+} getarg_collect_info;
+.Ed
+.Pp
+With the
+.Fa func
+member set to a function to call, and
+.Fa data
+to some application specific data. The parameters to the collect function are:
+.Bl -inset
+.It Fa short_flag
+non-zero if this call is via a short option flag, zero otherwise
+.It Fa argc , argv
+the whole argument list
+.It Fa optind
+pointer to the index in argv where the flag is
+.It Fa optarg
+pointer to the index in argv[*optind] where the flag name starts
+.It Fa data
+application specific data
+.El
+.Pp
+You can modify
+.Fa *optind ,
+and
+.Fa *optarg ,
+but to do this correct you (more or less) have to know about the inner
+workings of getarg.
+.Pp
+You can skip parts of arguments by increasing
+.Fa *optarg
+(you could
+implement the
+.Fl z Ns Ar 3
+set of flags from
+.Nm gzip
+with this), or whole argument strings by increasing
+.Fa *optind
+(let's say you want a flag
+.Fl c Ar x y z
+to specify a coordinate); if you also have to set
+.Fa *optarg
+to a sane value.
+.Pp
+The collect function should return one of
+.Dv ARG_ERR_NO_MATCH , ARG_ERR_BAD_ARG , ARG_ERR_NO_ARG, ENOMEM
+on error, zero otherwise.
+.Pp
+For your convenience there is a function,
+.Fn getarg_optarg ,
+that returns the traditional argument string, and you pass it all
+arguments, sans data, that where given to the collection function.
+.Pp
+Don't use this more this unless you absolutely have to.
+.El
+.Pp
+Option parsing is similar to what
+.Xr getopt
+uses. Short options without arguments can be compressed
+.Pf ( Fl xyz
+is the same as
+.Fl x y z ) ,
+and short
+options with arguments take these as either the rest of the
+argv-string or as the next option
+.Pf ( Fl o Ns Ar foo ,
+or
+.Fl o Ar foo ) .
+.Pp
+Long option names are prefixed with -- (double dash), and the value
+with a = (equal),
+.Fl Fl foo= Ns Ar bar .
+Long option flags can either be specified as they are
+.Pf ( Fl Fl help ) ,
+or with an (boolean parsable) option
+.Pf ( Fl Fl help= Ns Ar yes ,
+.Fl Fl help= Ns Ar true ,
+or similar), or they can also be negated
+.Pf ( Fl Fl no-help
+is the same as
+.Fl Fl help= Ns no ) ,
+and if you're really confused you can do it multiple times
+.Pf ( Fl Fl no-no-help= Ns Ar false ,
+or even
+.Fl Fl no-no-help= Ns Ar maybe ) .
+.Sh EXAMPLE
+.Bd -literal
+#include <stdio.h>
+#include <string.h>
+#include <getarg.h>
+
+char *source = "Ouagadougou";
+char *destination;
+int weight;
+int include_catalog = 1;
+int help_flag;
+
+struct getargs args[] = {
+ { "source", 's', arg_string, &source,
+ "source of shippment", "city" },
+ { "destination", 'd', arg_string, &destination,
+ "destination of shippment", "city" },
+ { "weight", 'w', arg_integer, &weight,
+ "weight of shippment", "tons" },
+ { "catalog", 'c', arg_negative_flag, &include_catalog,
+ "include product catalog" },
+ { "help", 'h', arg_flag, &help_flag }
+};
+
+int num_args = sizeof(args) / sizeof(args[0]); /* number of elements in args */
+
+const char *progname = "ship++";
+
+int
+main(int argc, char **argv)
+{
+ int optind = 0;
+ if (getarg(args, num_args, argc, argv, &optind)) {
+ arg_printusage(args, num_args, progname, "stuff...");
+ exit (1);
+ }
+ if (help_flag) {
+ arg_printusage(args, num_args, progname, "stuff...");
+ exit (0);
+ }
+ if (destination == NULL) {
+ fprintf(stderr, "%s: must specify destination\en", progname);
+ exit(1);
+ }
+ if (strcmp(source, destination) == 0) {
+ fprintf(stderr, "%s: destination must be different from source\en");
+ exit(1);
+ }
+ /* include more stuff here ... */
+ exit(2);
+}
+.Ed
+.Pp
+The output help output from this program looks like this:
+.Bd -literal
+$ ship++ --help
+Usage: ship++ [--source=city] [-s city] [--destination=city] [-d city]
+ [--weight=tons] [-w tons] [--no-catalog] [-c] [--help] [-h] stuff...
+-s city, --source=city source of shippment
+-d city, --destination=city destination of shippment
+-w tons, --weight=tons weight of shippment
+-c, --no-catalog include product catalog
+.Ed
+.Sh BUGS
+It should be more flexible, so it would be possible to use other more
+complicated option syntaxes, such as what
+.Xr ps 1 ,
+and
+.Xr tar 1 ,
+uses, or the AFS model where you can skip the flag names as long as
+the options come in the correct order.
+.Pp
+Options with multiple arguments should be handled better.
+.Pp
+Should be integrated with SL.
+.Pp
+It's very confusing that the struct you pass in is called getargS.

+.Os HEIMDAL
+.Sh NAME
+.Nm parse_time ,
+.Nm print_time_table ,
+.Nm unparse_time ,
+.Nm unparse_time_approx ,
+.Nd parse and unparse time intervals
+.Sh LIBRARY
+The roken library (libroken, -lroken)
+.Sh SYNOPSIS
+.Fd #include <parse_time.h>
+.Ft int
+.Fn parse_time "const char *timespec" "const char *def_unit"
+.Ft void
+.Fn print_time_table "FILE *f"
+.Ft size_t
+.Fn unparse_time "int seconds" "char *buf" "size_t len"
+.Ft size_t
+.Fn unparse_time_approx "int seconds" "char *buf" "size_t len"
+.Sh DESCRIPTION
+The
+.Fn parse_time
+function converts the period of time specified
+into a number of seconds.
+The
+.Fa timespec
+can be any number of
+.Aq number unit
+pairs separated by comma and whitespace. The number can be
+negative. Numbers without explicit units are taken as being
+.Fa def_unit .
+.Pp
+The
+.Fn unparse_time
+and
+.Fn unparse_time_approx
+do the opposite of
+.Fn parse_time ,
+that is they take a number of seconds and express that as human
+readable strings.
+.Fa unparse_time
+produces an exact time, while
+.Fa unparse_time_approx
+restricts the result to include only one unit.
+.Pp
+.Fn print_time_table
+prints a descriptive list of available units on the passed file
+descriptor.
+.Pp
+The possible units include:
+.Bl -tag -width "month" -compact -offset indent
+.It Li second , s
+.It Li minute , m
+.It Li hour , h
+.It day
+.It week
+seven days
+.It month
+30 days
+.It year
+365 days
+.El
+.Pp
+Units names can be arbitrarily abbreviated (as long as they are
+unique).
+.Sh RETURN VALUES
+.Fn parse_time
+returns the number of seconds that represents the expression in
+.Fa timespec
+or -1 on error.
+.Fn unparse_time
+and
+.Fn unparse_time_approx
+return the number of characters written to
+.Fa buf .
+if the return value is greater than or equal to the
+.Fa len
+argument, the string was too short and some of the printed characters
+were discarded.
+.Sh EXAMPLES
+.Bd -literal

+main(int argc, char **argv)

+ continue;
+ }
+ printf("--\\n");
+ printf("parse_time = %d\\n", result);
+ unparse_time(result, buf, sizeof(buf));

+.Ed
+.Sh BUGS
+Since
+.Fn parse_time
+returns -1 on error there is no way to parse "minus one second".
+Currently "s" at the end of units is ignored. This is a hack for
+English plural forms. If these functions are ever localised, this
+scheme will have to change.

+.Sh DESCRIPTION
+This set of functions assemble a simple table consisting of rows and
+columns, allowing it to be printed with certain options. Typical use
+would be output from tools such as
+.Xr ls 1
+or
+.Xr netstat 1 ,
+where you have a fixed number of columns, but don't know the column
+widths before hand.
+.Pp
+A table is created with
+.Fn rtbl_create
+and destroyed with
+.Fn rtbl_destroy .
+.Pp
+Global flags on the table are set with
+.Fa rtbl_set_flags
+and retrieved with
+.Fa rtbl_get_flags .
+At present the only defined flag is
+.Dv RTBL_HEADER_STYLE_NONE
+which suppresses printing the header.
+.Pp
+Before adding data to the table, one or more columns need to be
+created. This would normally be done with
+.Fn rtbl_add_column_by_id ,
+.Fa column_id
+is any number of your choice (it's used only to identify columns),
+.Fa column_header
+is the header to print at the top of the column, and
+.Fa flags
+are flags specific to this column. Currently the only defined flag is
+.Dv RTBL_ALIGN_RIGHT ,
+aligning column entries to the right. Columns are printed in the order
+they are added.
+.Pp
+There's also a way to add columns by column name with
+.Fn rtbl_add_column ,
+but this is less flexible (you need unique header names), and is
+considered deprecated.
+.Pp
+To add data to a column you use
+.Fn rtbl_add_column_entry_by_id ,
+where the
+.Fa column_id
+is the same as when the column was added (adding data to a
+non-existent column is undefined), and
+.Fa cell_entry
+is whatever string you wish to include in that cell. It should not
+include newlines.
+For columns added with
+.Fn rtbl_add_column
+you must use
+.Fn rtbl_add_column_entry
+instead.
+.Pp
+.Fn rtbl_new_row
+fills all columns with blank entries until they all have the same
+number of rows.
+.Pp
+Each column can have a separate prefix and suffix, set with
+.Fa rtbl_set_column_affix_by_id ;
+.Fa rtbl_set_column_prefix
+allows setting the prefix only by column name. In addition to this,
+columns may be separated by a string set with
+.Fa rtbl_set_separator ( Ns
+by default columns are not seprated by anything).
+.Pp
+The finished table is printed to
+.Fa file
+with
+.Fa rtbl_format .

+This program:
+.Bd -literal -offset xxxx

+#include <rtbl.h>
