NAME

rc_stringlist_add, rc_stringlist_addu, rc_stringlist_delete, rc_stringlist_free, rc_stringlist_new, rc_stringlist_sort —
RC string list functions

LIBRARY

Run Command library (librc, -lrc)

SYNOPSIS

#include <rc.h>

RC_STRINGLIST *
rc_stringlist_new(void);

RC_STRING *
rc_stringlist_add(RC_STRINGLIST *list, const char *item);

RC_STRING *
rc_stringlist_addu(RC_STRINGLIST *list, const char *item);

bool
rc_stringlist_delete(RC_STRINGLIST, const char *item);

void
rc_stringlist_free(RC_STRINGLIST *list);

void
rc_stringlist_sort(RC_STRINGLIST *list);

DESCRIPTION

These functions provide an easy means of manipulating string lists. They are basically wrappers around TAILQ macros found in queue(3).

rc_stringlist_new() creates a new list head to store the list.

rc_stringlist_add() adds a malloced copy of item to list. It returns a pointer to the new item on success, or NULL on failure and sets errno accordingly. rc_stringlist_addu() only works if list does not already contain item.

rc_stringlist_delete() removes and frees item from list, retuning true on success, otherwise false.

rc_stringlist_sort() sorts the list according to C locale.

rc_stringlist_free() frees each item on list and the list itself.
