NCBRECV

NCBRECV

This command receives data from the specified session name. If more than one command capable of receiving data is pending, they are processed in the following order:

1. Receive (NCBRECV)

2. Receive-any for a specified name (NCBRECVANY)

3. Receive-any for any name (NCBRECVANY)

All commands with the same precedence are processed in first-in, first-out (FIFO) order. If the buffer passed is not large enough to hold the data, the error NRC_INCOMP (0x06) is returned. If this occurs, issue another receive command with a larger buffer unless the send command was issued with either a timeout that expired or a no-ack—in which case the data is lost. The ncb_length field is set to the amount of data actually read on return. Table 22-18 describes the characteristics of the NCBRECV command.
