IMusicTechnology::SetTechnology method (portcls.h)

  • Article

The SetTechnology method changes the Technology member of each KSDATARANGE_MUSIC structure in the data ranges for the miniport driver's pins.

Syntax

NTSTATUS SetTechnology(
  [in] const GUID *Technology
);

Parameters

[in] Technology

Specifies a technology GUID. This parameter should point to one of the GUIDs that are defined for the Technology member of the KSDATARANGE_MUSIC structure.

Return value

SetTechnology returns STATUS_SUCCESS if the call was successful. Otherwise, the method returns an appropriate error code.

Remarks

The SetTechology method should be called before the miniport driver's Init method. If SetTechnology is not called, the miniport driver's Technology members are all set to KSMUSIC_TECHNOLOGY_PORT by default.

The following table lists the GUIDs that are defined for the Technology parameter and the corresponding integer value to which the wTechnology member of the MIDIOUTCAPS structure is set during a call to midiOutGetDevCaps.

Technology GUID MIDIOUTCAPS.wTechnology
KSMUSIC_TECHNOLOGY_PORT MOD_MIDIPORT
KSMUSIC_TECHNOLOGY_SQSYNTH MOD_SQSYNTH
KSMUSIC_TECHNOLOGY_FMSYNTH MOD_FMSYNTH
KSMUSIC_TECHNOLOGY_WAVETABLE MOD_WAVETABLE
KSMUSIC_TECHNOLOGY_SWSYNTH MOD_SWSYNTH
