The default value is returned when +/* no value was found. String results should be passed to myfree() +/* when no longer needed. \fImin\fR is zero or specifies a lower +/* bound on the string length; \fImax\fR is zero or specifies an +/* upper limit on the string length. +/* +/* get_mail_conf_str_fn() is similar but specifies a function that +/* provides the default value. The function is called only when +/* the default value is used. +/* +/* set_mail_conf_str() updates the named entry in the global +/* configuration dictionary. This has no effect on values that +/* have been looked up earlier via the get_mail_conf_XXX() routines. +/* +/* get_mail_conf_str_table() and get_mail_conf_str_fn_table() read +/* lists of variables, as directed by their table arguments. A table +/* must be terminated by a null entry. +/* +/* get_mail_conf_str2() concatenates the two names and is otherwise +/* identical to get_mail_conf_str(). +/* +/* check_mail_conf_str() exits with a fatal run-time error +/* when the string does not meet its length requirements. +/* DIAGNOSTICS +/* Fatal errors: bad string length. +/* SEE ALSO +/* config(3) generic config parameter support +/* LICENSE +/* .ad +/* .fi +/* The Secure Mailer license must be distributed with this software. +/* AUTHOR(S) +/* Wietse Venema +/* IBM T.J.
