Description

The pfnReleaseDescriptorInfo function releases a D3DKMDT_MONITOR_DESCRIPTOR structure that the VidPN manager previously provided to the display miniport driver.

A handle to a monitor descriptor set object. The display miniport driver previously obtained this handle by calling the pfnGetMonitorDescriptorSet function of the Monitor interface.

`pMonitorDescriptorInfo`

A pointer to the D3DKMDT_MONITOR_DESCRIPTOR structure to be released.

Return value

The pfnReleaseDescriptorInfo function returns one of the following values.

Return code	Description
STATUS_SUCCESS	The function succeeded.
STATUS_INVALID_MONITOR_DESCRIPTOR	The descriptor supplied in pMonitorDescriptorInfo was invalid.
STATUS_GRAPHICS_INVALID_MONITOR_DESCRIPTORSET	The handle supplied in hMonitorDescriptorSet was invalid.

Remarks

When you have finished using a D3DKMDT_MONITOR_DESCRIPTOR structure that you obtained by calling pfnAcquireFirstDescriptorInfo or pfnAcquireNextDescriptorInfo, you must release it by calling pfnReleaseDescriptorInfo.
