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.
