Linux 2.6 - man page for strncmp (linux section 3posix)

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

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 interpreted as type unsigned char) that differ
       in the strings being compared.

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.

ERRORS
       No errors are defined.
