The modifier of Data parameter: OUT VOID *Data -> OUT VOID *Data OPTIONAL The comments of Data parameter: Data The buffer to return the contents of the variable. -> Data The buffer to return the contents of the variable. May be NULL with a zero DataSize in order to determine the size buffer needed. The patch is to follow the spec to update the definition.
