NAME

       byte_diff - compare two strings

SYNTAX

       #include <byte.h>

       int byte_diff(const char *one,size_t len,const char *two);

DESCRIPTION

       byte_diff  returns  negative,  0, or positive, depending on whether the string one[0], one[1], ..., one[len-1] is lexicographically smaller
       than, equal to, or greater than the string one[0], one[1], ..., one[len-1].

       When the strings are different, byte_diff does not read bytes past the first difference.

NAME

     strcasecmp, strncasecmp -- compare strings, ignoring case

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <strings.h>

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

     int
     strncasecmp(const char *s1, const char *s2, size_t len);

DESCRIPTION

     The strcasecmp() and strncasecmp() functions compare the nul-terminated strings s1 and s2 and return an integer greater than, equal to, or
     less than 0, according to whether s1 is lexicographically greater than, equal to, or less than s2 after translation of each corresponding
     character to lower-case.  The strings themselves are not modified.  The comparison is done using unsigned characters, so that '200' is
     greater than ''.

     The strncasecmp() compares at most len characters.

SEE ALSO

     bcmp(3), memcmp(3), strcmp(3), strcoll(3), strxfrm(3)

HISTORY

     The strcasecmp() and strncasecmp() functions first appeared in 4.4BSD.

NOTES

     If len is zero strncasecmp() returns always 0.
