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.
