STRNCMP(P)		   POSIX Programmer's Manual		    STRNCMP(P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       strncmp - compare part of two strings

SYNOPSIS
       #include <string.h>

       int strncmp(const char *s1, const char *s2, size_t n);

DESCRIPTION
       The strncmp() function shall compare not more than n bytes (bytes  that
       follow a null byte are not compared) from the array pointed to by s1 to
       the array pointed to by s2.

       The sign of a non-zero return value is determined by the	 sign  of  the
       difference  between  the values of the first pair of bytes (both inter‐
       preted as type unsigned char) that differ in  the  strings  being  com‐
       pared.

RETURN VALUE
       Upon  successful	 completion, strncmp() shall return an integer greater
       than, equal to, or less than 0, if the possibly	null-terminated	 array
       pointed	to  by s1 is greater than, equal to, or less than the possibly
       null-terminated array pointed to by s2 respectively.
