Usage
#include <stringlist.h>
StringList *
sl_init();

Overview
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.
