NAME¶
wctrans - wide-character translation mapping
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. Non-zero 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.
CONFORMING TO¶
C99.
NOTES¶
The behavior of wctrans() depends on the LC_CTYPE category of the current locale.
