MoFreeMediaType
The MoFreeMediaType function frees the allocated members of a media type structure.
Syntax
HRESULT MoFreeMediaType(
DMO_MEDIA_TYPE *pmt
);
Parameters
pmt
Pointer to an initialized DMO_MEDIA_TYPE structure.
Return Value
Returns an HRESULT value. Possible values include the following.
| Result Code | Description |
| E_POINTER | NULL pointer argument |
| S_OK | Success |
Remarks
Call this function to free a format block that was allocated with the MoInitMediaType function. This function frees the pbFormat member of the DMO_MEDIA_TYPE structure and sets pbFormat to NULL. The function does not reset the cbFormat member to zero, however, so if you re-use the DMO_MEDIA_TYPE structure, you should set cbFormat to zero.
Requirements
Header: Declared in Dmort.h; include Dmo.h
Library: Msdmo.lib.
