IPCCHECK

Returns the number of the last applicable error.

Syntax

IPCCHECK  (descriptor [,ipcerr][,pmerr][,result]

Parameters

descriptor (input): 32-bit integer, by value. The call socket or VC socket descriptor for which the error is to be reported. A zero value indicates the last call socket or VC socket descriptor referenced.
ipcerr (output): 32-bit integer, by reference. The error code of the last recorded NetIPC error.
pmerr (output): 32-bit integer, by reference. The error code of the last recorded protocol module (i.e., the Transmission Control Protocol (TCP) or X.25 protocol).
result (output): 32-bit integer, by reference. The error code returned for this intrinsic call (not the previously recorded error). A zero value indicates no error.

Description

The IPCCHECK intrinsic returns the last recorded NetIPC and/or protocol module error for a given call socket or VC socket (that is, the VC socket descriptor at the calling process's end). If the descriptor value is zero, the most recent error applicable to the last call or VC socket referenced is returned. The descriptor is the only required parameter (option variable).

Condition codes returned by this intrinsic are:

CCE — The intrinsic call was successful.
CCL — Unsuccessful.
CCG — Unsuccessful. The intrinsic could not return the error code because the calling process does not have access to the NetIPC data structure which retains error codes.

This intrinsic can be called in split stack mode.
