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.
