KSAUDIOMODULE_DESCRIPTOR structure (ksmedia.h)
The KSAUDIOMODULE_DESCRIPTOR structure describes the static, external properties of audio modules.
Syntax
typedef struct _KSAUDIOMODULE_DESCRIPTOR {
GUID ClassId;
ULONG InstanceId;
ULONG VersionMajor;
ULONG VersionMinor;
WCHAR Name[AUDIOMODULE_MAX_NAME_CCH_SIZE];
} KSAUDIOMODULE_DESCRIPTOR, *PKSAUDIOMODULE_DESCRIPTOR;
Members
ClassId
The ClassId of the audio module. The ClassId is an identifier that establishes what type of module this is. The value and mapping is established by the ISV and IHV.
InstanceId
The InstanceId of the audio module. The InstanceId is a unique identifier that distinguishes this instance of a module from another instance of a module.
VersionMajor
The major version of the audio module. Usage is defined by the implementer.
VersionMinor
The minor version of the audio module. Usage is defined by the implementer.
Name[AUDIOMODULE_MAX_NAME_CCH_SIZE]
The friendly name of the audio module. The maximum length is AUDIOMODULE_MAX_NAME_CCH_SIZE wide characters. It is defined as 128 in KSMedia.h.
