The function returns a unique identifier (HOBJ) of object of the Process type that called currently executed RPC procedure.
Declaration
INT %GetRPCCallerProcess()
Parameters
No parameters.
Return value
The return value is of the Int type.
Description
This function can be used to identify the process in an application that is built on server-client architecture. It eliminates the explicit transmission of process identifier by means of parameters. This example shows the transmission of identifier of calling process by means of parameter:
Example
; Calling with transmission of HOBJ of calling process
INT _hbj
_hbj := %GetParentProcessHBJ()
CALL [E.Service] Service(1, _hbj)
; *****************************************
; _callerProcess - HOBJ of calling process
RPC PROCEDURE Service (IN INT _anyParams, IN INT _callerProcess)
END Service
or using the function %GetRPCCallerProcess:
; Calling without transmission of HOBJ by means of parameter
CALL [E.Service] Service(1)
;
RPC PROCEDURE Service (IN INT _anyParams, IN INT _callerProcess)
INT _callerProcess
_callerProcess := %GetRPCCallerProcess()
END Service
