Typedef Documentation

unsigned int(* LSD_sdiWriteRtn)(void *prm, LSD_sdiPds *pds)

Function to post a completed packet to the SDI.

Parameters:

	prm	User parameter
	pds	The packet descriptor structure of the data to be written

This callback normally would call ITC_send. Making this a callback, allows the user to intercept the call.
