towctrans - map wide characters

Syntax

#include <wctype.h> wint_t towctrans(wint_t wc, wctrans_t desc);

	current value of the category LC_CTYPE must be the same as the one valid for the towctrans() call that returned the value desc. The two following calls to towctrans() have the same affect as the calls for converting to small or capital letters shown in the corresponding comments:
	towctrans(wc, wctrans("tolower")) towctrans(wc, wctrans("toupper"))	/* towlower(wc) */ /* towupper(wc) */
Return val.	transformed wide character if successful.
Notes	In this version of the C runtime system, only 1 byte characters are supported as wide characters.
