pktXinitBuffers

int pktXinitBuffers( int buf_count, int buf_size ); /* X is A-F */

Description

Allocates extended memory for channel X receive buffers. This function should not be called more than once in a program. The total memory allocated is buf_count*(buf_size + 2) bytes.

The functions pktEinitBuffers() and pktFinitBuffers() may be used with the Rabbit 3000 and Rabbit 4000.

Parameters

buf_count

The number of buffers to allocate. Each buffer can store one received packet. Increasing this number allows for more pending packets and a larger latency time before packets must be processed by the user's program.

buf_size

The number of bytes each buffer can accommodate. This should be set to the size of the largest possible packet that can be expected.

Return value

1: Success, extended memory was allocated.
0: Failure, no memory allocated, the packet channel cannot be used.
