wint_t towupper( wint_t ch );

Converts the given wide character to uppercase, if possible.


[edit] Parameters

ch - wide character to be converted

[edit] Return value

Uppercase version of ch or unmodified ch if no uppercase version is listed in the current C locale.

[edit] Notes

Only 1:1 character mapping can be performed by this function, e.g. the uppercase form of 'ß' is (with some exceptions) the two-character string "SS", which cannot be obtained by towupper.
