BPX1RCV (recv) example

The following code issues a recv for a socket. SOCKDESC was returned previously from a call to either BPX1SOC or BPX1ACP. For the callable service, see recv (BPX1RCV, BPX4RCV) — Receive data on a socket and store it in a buffer. For the data structures, see BPXYSOCK — Map SOCKADDR structure and constants and BPXYMSGF — Map the message flags. AMODE 64 callers use BPX4RCV (recv) example.
