sl_free(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, 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's not found.
