The IsCharUpper function determines whether a character is uppercase. This determination is based on the semantics of the language selected by the user during setup or by using Control Panel.
BOOL IsCharUpper(
|
TCHAR ch |
// character to test |
|
); |
If the character is uppercase, the return value is nonzero.
If the character is not uppercase, the return value is zero. To get extended error information, call GetLastError.
