IDARG_IN_GETSRMLISTVERSION is an input structure for IddCxMonitorGetSrmListVersion.
SrmListVersionBufferInputCount [in]Size in bytes of the buffer being passed by the driver to the OS through pSrmListVersion. A value of zero indicates that the driver is simply querying the size of the SRM list version buffer that should be provided by the driver. In this case, the OS will set the buffer size in the output structure.
Either SrmListVersionBufferInputCount needs to be zero and pSrmListVersion set to null, or SrmListVersionBufferInputCount needs to be non-zero and pSrmListVerion needs to be non-null.
pSrmListVerionPointer to a buffer in which the OS should copy the SRM list version if the value is non-NULL. In this case, the format of the version is defined by the PlayReady Porting Kit 4.0.
If pSrmListVerion is NULL then the OS will not copy any data and will set the value IDARG_OUT_GETSRMLISTVERSION.SrmListVersionBufferOutputCount to indicate the size of buffer required to store the SRM list version.
