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 .

ATTRIBUTES

For an explanation of the terms used in this section, see attributes (7).
