SYNOPSIS

In bsd/stringlist.h Ft StringList * Fn sl_init void Ft int Fn sl_add StringList *sl char *item Ft void Fn sl_free StringList *sl int freeall Ft char * Fn sl_find StringList *sl const char *item Ft int Fn sl_delete StringList *sl const char *item int freeit

DESCRIPTION

The 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:

Fn sl_init

Create a stringlist. Returns a pointer to a StringList or NULL in case of failure.

Fn 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.

Fn 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.

Fn sl_find

Find item in sl returning NULL if it's not found.

Fn 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.

HISTORY

The functions appeared in Fx 2.2.6 and Nx 1.3 .
