wctrans — wide-character translation mapping
#include <wctype.h>
wctrans_t
wctrans( |
const char *name); |
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
The wctrans() function
returns a mapping descriptor if the name is valid. Otherwise, it
returns (wctrans_t)
0.
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.
