Receives network-specific data each time it is coded by the kernel user and called by generic data link control (GDLC).
int (*dlc_open_ext.rcvn_fa)(m, ext) struct mbuf *m; struct dlc_io_ext *ext;
The DLC Network Data Received routine receives network-specific data each time the routine is coded by the kernel user and called by GDLC.
|m||Points to a communications memory buffer (mbuf).|
|ext||Specifies the receive extension parameter. This is a pointer to the dlc_io_ext extended I/O structure for read operations.|
|DLC_FUNC_OK||Indicates that the received network mbuf data has been accepted.|
|DLC_FUNC_RETRY||Indicates that the received network mbuf data cannot be accepted at this time. GDLC should retry this function call later. The actual retry wait period depends on the DLC in use. Excessive retries can cause a disabling of the service access point.|
Each GDLC supports a subset of the data-received routines. It is critical to performance that the Network Data Received routine be coded to minimize the amount of time spent prior to returning to the GDLC that called it.
