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. 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

 

Multithreading (see pthreads(7))

The wctrans() function is thread-safe with exceptions. It can be safely used in multithreaded applications, as long as setlocale(3) is not called to change the locale during its execution.  

CONFORMING TO

C99.  

NOTES

The behavior of wctrans() depends on the LC_CTYPE category of the current locale.
