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.
