wctrans(3) Library Functions Manual wctrans(3)
NAME
wctrans - wide-character translation mapping
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wctype.h>
wctrans_t wctrans(const char *name);
DESCRIPTION
The wctrans_t type represents a mapping which can map a wide character
to another wide character. Its nature is implementation-dependent, but
the special value (wctrans_t) 0 denotes an invalid mapping. Nonzero
wctrans_t values can be passed to the towctrans(3) function to actually
perform the wide-character mapping.
The wctrans() function returns a mapping, given by its name. The set
of valid names depends on the LC_CTYPE category of the current locale,
but the following names are valid in all locales.
"tolower" - realizes the tolower(3) mapping
"toupper" - realizes the toupper(3) mapping
RETURN VALUE
The wctrans() function returns a mapping descriptor if the name is
valid. Otherwise, it returns (wctrans_t) 0.
