NetIPC Intrinsics
IPCRECVCN
IPCRECVCN and the IOWAIT intrinsic calls. NetIPC also retains the
flags
parameter.
The only required parameters are the
calldesc
and
vcdesc
parameters (option variable). Condition codes returned by this intrinsic
are:
• CCE — Succeeded.
• CCL — Failed.
• CCG — Not returned by this intrinsic.
Condition codes returned by the call to IOWAIT are:
• CCE — Succeeded.
• CCL — Failure in NetIPC (for example, resource problems, VC
socket descriptor bounds) or protocol module. In the event of a
NetIPC failure the connection request will still be pending, allowing
the user to correct the problem and issue another call to IPCRECVCN.
• CCG — Connection established but a noncritical error (for example,
flags parameter out of bounds) occurred.
The IPCRECVCN intrinsic cannot be called in split stack mode.
