ICSetState

The ICSetState macro notifies a video compression driver to set the state of the compressor. You can use this macro or explicitly call the ICM_SETSTATE message.

DWORD ICSetState(

hic,
pv,
cb
);

Parameters

hic

Handle of the compressor.

pv

Address of a block of memory containing configuration data. You can specify NULL for this parameter to reset the compressor to its default state.

cb

Size, in bytes, of the block of memory.

Return Values

Returns the number of bytes used by the compressor if successful or zero otherwise.

Remarks

The information used by this message is private and specific to a given compressor. Client applications should use this message only to restore information previously obtained with the ICGetState and ICConfigure macros and should use the ICConfigure macro to adjust the configuration of a video compression driver.
