Description
Returns the maximum number of characters that can be stored in a PWideChar allocated by WStrAlloc.
WStrBufSize returns the number of characters in Str, including the byte for the termination character.
Note: If Str does not point to a string buffer allocated by WStrAlloc or WStrNew, no error message is returned, and the result is unpredictable.
