STRINGLIST(3)						   BSD Library Functions Manual 					     STRINGLIST(3)

NAME
stringlist, sl_init, sl_add, sl_free, sl_find -- stringlist manipulation functions LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stringlist.h> StringList * sl_init(); int sl_add(StringList *sl, char *item); void sl_free(StringList *sl, int freeall); char * sl_find(StringList *sl, const char *item); DESCRIPTION
The stringlist functions manipulate stringlists, which are lists of strings that extend automatically if necessary. The StringList structure has the following definition: typedef struct _stringlist { char **sl_str; size_t sl_max; size_t sl_cur; } StringList; sl_str a pointer to the base of the array containing the list. sl_max the size of sl_str. sl_cur the offset in sl_str of the current element. The following stringlist manipulation functions are available: sl_init() Create a stringlist. Returns a pointer to a StringList, or NULL in case of failure. sl_free() Releases memory occupied by sl and the sl->sl_str array. If freeall is non-zero, then each of the items within sl->sl_str is released as well. sl_add() Add item to sl->sl_str at sl->sl_cur, extending the size of sl->sl_str. Returns zero upon success, -1 upon failure. sl_find() Find item in sl, returning NULL if it is not found. SEE ALSO
