IDirectMusicPerformance::AssignPChannelBlock

  • Article

This method assigns a block of 16 performance channels (PChannels) to the performance and maps them to a port and a channel group. This method must be called when a port has been added to a performance, except when the default port has been added by passing NULL to IDirectMusicPerformance::AddPort.

HRESULT AssignPChannelBlock(
  DWORD dwBlockNum,
  IDirectMusicPort* pPort,
  DWORD dwGroup
);

Parameters

  • dwBlockNum
    Block number, in which 0 represents channels 0 through 15, 1 represents channels 16 through 31, and so on.
  • pPort
    Address of a variable that contains the port to which the channels are assigned.
  • dwGroup
    Channel group on the port. Must be 1 or greater.

Return Values

If the method succeeds, the return value is S_OK or S_FALSE (see Remarks).

If it fails, the method can return one of the following error values:

E_INVALIDARG
E_POINTER

Remarks

The method returns S_FALSE if dwGroup is out of the range of the port. The channels have been assigned, but the port cannot play this group.

The method returns E_INVALIDARG if the port has not been added to the performance through a call to the IDirectMusicPerformance::AddPort method.

Requirements

OS Versions: Windows CE .NET 4.0 and Windows CE .NET 4.1.
Header: Dmusici.h.
Link Library: Dmusic.lib.
