.Nd RC string list functions
.Sh LIBRARY
Run Command library (librc, -lrc)
.Sh SYNOPSIS
.In rc.h
.Ft "RC_STRINGLIST *" Fn rc_stringlist_new void
.Ft "RC_STRING *" Fn rc_stringlist_add "RC_STRINGLIST *list" "const char *item"
.Ft "RC_STRING *" Fn rc_stringlist_addu "RC_STRINGLIST *list" "const char *item"
.Ft bool Fn rc_stringlist_delete RC_STRINGLIST "const char *item"
.Ft void Fn rc_stringlist_free "RC_STRINGLIST *list"
.Ft void Fn rc_stringlist_sort "RC_STRINGLIST *list"
.Sh DESCRIPTION
These functions provide an easy means of manipulating string lists. They are
basically wrappers around TAILQ macros found in
.Xr queue 3 .
.Pp
.Fn rc_stringlist_new
creates a new list head to store the list.
.Pp
.Fn rc_stringlist_add
adds a malloced copy of
.Fa item
to
.Fa list .
It returns a pointer to the new item on success, or NULL on failure and sets
.Va errno
accordingly.
.Fn rc_stringlist_addu
only works if
.Fa list
does not already contain
.Fa item .
.Pp
.Fn rc_stringlist_delete
removes and frees
.Fa item
from
.Fa list ,
retuning true on success, otherwise false.
.Pp
.Fn rc_stringlist_sort
sorts the
.Fa list
according to C locale.
.Pp
.Fn rc_stringlist_free
frees each item on
.Fa list
and the
.Fa list
itself.
