LSEARCH(3) Linux Programmer's Manual LSEARCH(3)
NAME
lfind, lsearch - linear search of an array.
SYNOPSIS
#include <stdlib.h>
void *lfind(const void *key, const void *base, size_t *nmemb,
size_t size, int (*compar)(const void *, const void *));
void *lsearch(const void *key, const void *base, size_t *nmemb,
size_t size, int (*compar)(const void *, const void *));
DESCRIPTION
lfind() and lsearch() perform a linear search for key in
the array base which has *nmemb elements of size bytes
each. The comparison function referenced by compar is
expected to have two arguments which point to the key
object and to an array member, in that order, and which
returns zero if the key object matches the array member,
and non-zero otherwise.
If lsearch() does not find a matching element, then the
key object is inserted at the end of the table, and *nmemb
is incremented.
RETURN VALUE
lfind() returns a pointer to a matching member of the
array, or NULL if no match is found. lsearch() returns a
pointer to a matching member of the array, or to the newly
added member if no match is found.
