Queue size

Collaboration diagram for Queue size:

Functions
void WINAPI	vpb_set_global_apiq_size (int size)
	Set the maximum number of events the global APIQ may hold.
void WINAPI	vpb_set_channel_apiq_size (int size)
	Set the maximum number of events per-channel APIQ's may hold.

Detailed Description

Note

These functions must be called prior to the initialisation of the device structures. That means before any call to vpb_open(), vpb_get_num_cards(), or vpb_get_ports_per_card() is made.

Exceptions

VpbException

will be thrown if they are called after device initialisation has taken place.

If you really must change them after that, you may call vpb_close(), (with no arguments) to close all ports and release the existing device structures, then call them before re-opening the desired ports.
