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.
