DEV_OPEN_IFACE - Open device driver interface
Interrupt 0xAC service 0xA2: DEV_RECV_IFACE, Move received data
Parameters
AH
ES:DI
Receive and process incoming data at the TCP/IP stack.
0xA2 (=DEV_RECV_IFACE)
Device handle from the IfaceHandle member of the DevUserDriver structure used at the
DEV_OPEN_IFACE call.
Return Value
Comments
DX = 0, AX = 0: Success.
DX = -1: Failure, AX contains error code
255: Insufficient memory to complete operation
This function must be called to process incoming data on the TCP/IP stack. This function in turn calls the
driver receive function (specified by the DevRecv member of the DevUserDriver structure at the
DEV_OPEN_IFACE call) and inserts the received data into the receive queue of the matching socket (if there
is one). Any tasks waiting on the socket (sleeping at RECV or RECVFROM ) are then signaled that there is
new data available. Only IGMP and ARP requests are directly processed in the task which does this call.
Do not call this API from inside of an ISR!
This function should be used only in combination with the Wait for receive event API call in the user's receiver
task for their device driver interface.
