Name
towctrans
Synopsis
Performs a locale-specific conversion on a wide character
#include <wctype.h> wint_ttowctrans
( wint_twc
, wctrans_tdesc
);
The towctrans()
function
returns a wide character that corresponds to the wide character
value of its first argument, wc
,
according to a locale-specific mapping described by the second
argument, desc
. Values of
desc
are obtained by calling the wctrans()
function. The behavior of both
wctrans()
and towctrans()
is dependent on the locale
setting of the category LC_CTYPE
,
which must not change between the two function calls.
Example
wint_t before = L'\0', after = L'\0'; wctrans_t mapping; mapping = wctrans("toupper"); while (( before = getwchar() ) != WEOF ) { after = towctrans( before, mapping ); putwchar( after ); if ( after == L'Q' ) break; }
