mciGetErrorString - Parameters

ulError (ULONG) - input

Specifies the error code. The low-order word contains the error code and the high-order word contains the device ID.

pszBuffer (PSZ) - output

Pointer to the application's buffer. The textual error string will be copied to this buffer based on the length of the buffer.

usLength (USHORT) - input

Specifies the size of the application's buffer.
