NAME

       str_diff - compare two ASCIIZ strings

SYNTAX

       #include <str.h>

       int str_diff(const char* a,const char* b);

DESCRIPTION

       str_diff  returns  negative, 0, or positive, depending on whether the string a[0], a[1], ..., a[n]=='' is lexicographically smaller than,
       equal to, or greater than the string b[0], b[1], ..., b[m-1]==''.

       If the strings are different, str_diff does not read bytes past the first difference.

NAME

     strcmp, strncmp -- compare strings

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     int
     strcmp(const char *s1, const char *s2);

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

DESCRIPTION

     The strcmp() and strncmp() functions lexicographically compare the null-terminated strings s1 and s2.

     The strncmp() function compares not more than n characters.  Because strncmp() is designed for comparing strings rather than binary data,
     characters that appear after a '' character are not compared.

RETURN VALUES

     The strcmp() and strncmp() functions return an integer greater than, equal to, or less than 0, according as the string s1 is greater than,
     equal to, or less than the string s2.  The comparison is done using unsigned characters, so that '200' is greater than ''.

STANDARDS

     The strcmp() and strncmp() functions conform to ISO/IEC 9899:1990 (``ISO C90'').
