NetIPC Intrinsics
IO[DONT]WAIT
If a nowait IPCSEND, IPCRECVCN,orIPCRECV request is issued, the data
and flags parameters (if specified) must exist when IOWAIT or
IODONTWAIT is called. In other words, these parameters must be global
to both the IPC intrinsic that initiates the request and the
IO[DONT]WAIT that attempts to complete the I/O.
All parameters are optional (option variable). In general, the condition
codes returned by IOWAIT/IODONTWAIT for socket I/O have the following
meanings:
• CCE — Succeeded.
• CCL — Failed.
• CCG — The operation succeeded but a noncritical error occurred (for
example, the flags parameter was out of bounds).
IOWAIT and IODONTWAIT can be called in split stack mode.
