NAME
     lsearch, lfind -- linear searching routines

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <search.h>

     void *
     lsearch(const void *key, void *base, size_t *nelp, size_t width, int (*compar)(const void *, const void *));

     void *
     lfind(const void *key, const void *base, size_t *nelp, size_t width, int (*compar)(const void *, const void *));

DESCRIPTION
     The functions lsearch(), and lfind() provide basic linear searching functionality.

     base is the pointer to the beginning of an array.	The argument nelp is the current number of elements in the array, where each element is
     width bytes long.	The compar argument points to a function which compares its two arguments and returns zero if they are matching, and non-
     zero otherwise.

     The lsearch() and lfind() functions return a pointer into the array referenced by base where key is located.  If key does not exist, lfind()
     will return a null pointer and lsearch() will add it to the array.  When an element is added to the array by lsearch() the location refer-
     enced by the argument nelp is incremented by one.

STANDARDS
     The lsearch() and lfind() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
