NAME
     towctrans, wctrans — wide character mapping functions

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <wctype.h>

     wint_t
     towctrans(wint_t wc, wctrans_t desc);

     wctrans_t
     wctrans(const char *charclass);

DESCRIPTION
     The wctrans() function returns a value of type wctrans_t which represents
     the requested wide character mapping operation and may be used as the
     second argument for calls to towctrans().

     The following character mapping names are recognised:

	   tolower    toupper

     The towctrans() function transliterates the wide character wc according
     to the mapping described by desc.

RETURN VALUES
     The towctrans() function returns the transliterated character if success‐
     ful, otherwise it returns the character unchanged and sets errno.

     The wctrans() function returns non-zero if successful, otherwise it
     returns zero and sets errno.

EXAMPLES
     Reimplement towupper() in terms of towctrans() and wctrans():

	   wint_t
	   mytowupper(wint_t wc)
	   {
		   return (towctrans(wc, wctrans("toupper")));
	   }

ERRORS
     The towctrans() function will fail if:

     [EINVAL]		The supplied desc argument is invalid.

     The wctrans() function will fail if:

     [EINVAL]		The requested mapping name is invalid.

SEE ALSO
     tolower(3), toupper(3), wctype(3)

STANDARDS
     The towctrans() and wctrans() functions conform to IEEE Std 1003.1-2001
     (“POSIX.1”).

HISTORY
     The towctrans() and wctrans() functions first appeared in FreeBSD 5.0.
