   hic,

);

Parameters

Handle of the compressor.

pv

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

Size, in bytes, of the block of memory.

Return value

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.
