Return the maximum packet size associated to packetized file handle.

If the file is not packetized (stream like http or file on disk), then 0 is returned.

Parameters:

h

file handle

Returns:

maximum packet size in bytes

the callback is called in blocking functions to test regulary if asynchronous interruption is needed.

AVERROR(EINTR) is returned in this case by the interrupted function. 'NULL' means no interrupt callback is given. i
