NAME

       case - convert ASCII uppercase bytes to lowercase

SYNTAX

       #include <case.h>

       void case_lowers(s);
       void case_lowerb(s,len);

       int case_diffs(s,t);
       int case_equals(s,t);
       int case_starts(s,t);

       int case_diffb(s,len,t);
       int case_startb(s,len,t);

       char *s;
       char *t;
       unsigned int len;

DESCRIPTION

       case_lowers  converts  each  uppercase  byte  in  the  string  s  to lowercase.  s must be
       0-terminated.

       case_lowerb converts each uppercase byte in the buffer s, of length len, to lowercase.

       case_diffs lexicographically compares lowercase versions of  the  strings  s  and  t.   It
       returns something positive, negative, or zero when the first is larger than, smaller than,
       or equal to the second.  s and t must be 0-terminated.

       case_equals means !case_diffs.

       case_starts returns 1 if a lowercase version of s starts with a lowercase version of t.  s
       and t must be 0-terminated.

       case_diffb  lexicographically  compares lowercase versions of the buffers s and t, each of
       length len.  It returns something positive, negative, or zero when  the  first  is  larger
       than, smaller than, or equal to the second.

       case_startb returns 1 if a lowercase version of the buffer s, of length len, starts with a
       lowercase version of the string t.  t must be 0-terminated.

       The case routines are ASCII-specific.  They are suitable for programs  that  handle  case-
       independent networking protocols.

       All comparisons are performed on unsigned bytes.
