Detailed Description

Function Documentation

PROCESS_THREAD	(	usb_eth_process	,
		ev	,
		data_proc
	)

RNDIS Process.

This is the link between USB and the "good stuff". In this routine data is received and processed by RNDIS, CDC-ECM, or CDC-EEM

uint8_t rndis_get_encapsulated_command

(

void

)

Handle "GET ENCAPSULATED COMMAND".

Returns

True on success, false on failure.

This function assumes the message has already set up in the "encapsulated_buffer" variable. This will be done by the "SEND ENCAPSULATED COMMAND" message, which will trigger and interrupt on the host so it knows data is ready.

< Send data until necessary

< Check endpoint 0 size

uint16_t

wLength

)
