StringList *
sl_init
(void);
int
sl_add
(StringList

sl_free
(StringList
*sl, int
freeall);

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;
where:
- sl_str
- is a pointer to the base of the array containing the list,
- sl_max
- is the size of sl_str, and
- sl_cur
- is 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.
