BOOL PWAVFile::Open ( OpenMode  mode = ReadWrite,
int  opts = ModeDefault 
) [virtual]

Open the current file in the specified mode and with the specified options. If the file object already has an open file then it is closed.

If there has not been a filename attached to the file object (via SetFilePath()#, the name# parameter or a previous open) then a new unique temporary filename is generated.

TRUE if the file was successfully opened.
mode  Mode in which to open the file.
opts  Options for open operation.
