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.
