NAME

stringlist, sl_init, sl_add, sl_free, sl_find, sl_delete - stringlist manipulation functions

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS



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)

int sl_delete(StringList *sl, const char *item, int freeit)

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's not found.

sl_delete()
Remove item from the list. If freeit is non-zero, the string is freed. Returns 0 if the name is found and -1 if the name is not found.
