/* NAME
/* argv_split 3
/* SUMMARY
/* string array utilities
/* SYNOPSIS
/* #include <argv.h>
/*
/* ARGV *argv_split(string, delim)
/* const char *string;
/* const char *delim;
/*
/* ARGV *argv_split_count(string, delim, count)
/* const char *string;
/* const char *delim;
/* ssize_t count;
/*
/* ARGV *argv_split_append(argv, string, delim)
/* ARGV *argv;
/* const char *string;
/* const char *delim;
/* DESCRIPTION
/* argv_split() breaks up \fIstring\fR into tokens according
/* to the delimiters specified in \fIdelim\fR. The result is
/* a null-terminated string array.
/*
/* argv_split_count() is like argv_split() but stops splitting
/* input after at most \fIcount\fR -1 times and leaves the
/* remainder, if any, in the last array element. It is an error
/* to specify a count < 1.
/*
/* argv_split_append() performs the same operation as argv_split(),
/* but appends the result to an existing string array.
/* SEE ALSO
/* mystrtok(), safe string splitter.
/* DIAGNOSTICS
/* Fatal errors: memory allocation problem.
/* LICENSE
/* .ad
