ICGetStateSize
The ICGetStateSize
macro queries a video compression driver to determine the amount of memory
required to retrieve the configuration information. You can use this macro or
explicitly call the ICM_GETSTATE
message.
DWORD ICGetStateSize(
|
hic |
|
|
); |
|
Parameters
hic
Handle of the
compressor.
Return Values
Returns the
amount of memory, in bytes, required by the state information.
Remarks
The structure
used to represent configuration information is driver specific and is defined
by the driver.
Use ICGetStateSize
before calling the ICGetState macro to determine the size of buffer to
allocate for the call.
