   wctrans.c Extensible wide-character case mapping functions

#include <string.h>
#include <wctype.h>

   This differs from the MS implementation of wctrans which
   returns 0 for tolower and 1 for toupper.  According to
   C99, a 0 return value indicates invalid input.

   These two function go in the same translation unit so that we
   can ensure that
     towctrans(wc, wctrans("tolower")) == towlower(wc) 
     towctrans(wc, wctrans("toupper")) == towupper(wc)
   It also ensures that
     towctrans(wc, wctrans("")) == wc
   which is not required by standard.

static const struct {
  const char *name;
  wctrans_t val; } tmap[] = {
    {"tolower", _LOWER},
    {"toupper", _UPPER}

#define     NTMAP (sizeof tmap / sizeof tmap[0])

wctrans (const char* property)
  int i;
  for ( i = 0; i < (int) NTMAP; ++i )
    if (strcmp (property, tmap[i].name) == 0)
      return tmap[i].val;
   return 0;

wint_t towctrans (wint_t wc, wctrans_t desc)
  switch (desc)
    case _LOWER:
      return towlower (wc);
    case _UPPER:
      return towupper (wc);
      return wc;
