Defined in header <wctype.h>
wctrans_t wctrans( const char* str );		(since 哋它亢95)

Constructs a value of type wctrans_t that describes a LC_CTYPE category of wide character mapping. It may be one of the standard mappings, or a locale-specific mapping, such as "tojhira" or "tojkata".

Parameters

str

-

C string holding the name of the desired mapping. The following values of str are supported in all C locales: Value of str Effect "toupper" identifies the mapping used by towupper "tolower" identifies the mapping used by towlower

Return value

wctrans_t object suitable for use with towctrans to map wide characters according to the named mapping of the current C locale or zero if str does not name a mapping supported by the current C locale.
