NAME

       lfind, lsearch - linear search of an array.

SYNOPSIS

       #include <search.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, 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.
