Function Documentation

◆ coap_debug_send_packet()

int coap_debug_send_packet ( void )

Check to see whether a packet should be sent or not.

Internal function

Returns: 1 if packet is to be sent, 0 if packet is to be dropped.

◆ coap_debug_set_packet_loss()

int coap_debug_set_packet_loss ( const char * loss_level )

Set the packet loss level for testing.

This can be in one of two forms.

Percentage : 0% to 100%. Use the specified probability. 0% is send all packets, 100% is drop all packets.

List: A comma separated list of numbers or number ranges that are the packets to drop.

Parameters

loss_level The defined loss level (percentage or list).

Returns: 1 If loss level set, 0 if there is an error.
