The EnumMasterClock method enumerates the clocks that DirectMusic can use as the master clock. Each time it is called, this method retrieves information about a single clock.
HRESULT EnumMasterClock( DWORD dwIndex, LPDMUS_CLOCKINFO lpClockInfo );
Index of the clock for which the description is to be returned. This parameter should be 0 on the first call, and then incremented in each subsequent call until S_FALSE is returned.
Address of a DMUS_CLOCKINFO8 structure that receives the description of the clock. The application must initialize the dwSize member of this structure before passing the pointer.
If the method succeeds, the return value is S_OK, or S_FALSE if there is no clock with that index number.
If it fails, the method can return one of the error values shown in the following table.
Applications should not rely on or store the index number of a clock. Rebooting or adding and removing hardware can cause the index number of a clock to change.
