ErsStart - Startup Error reporting system.

Function

Startup Error reporting system.

Description

Startup the Error reporting system. Calls may be made to the other Ers routines without calling this routine, but if this is done, then messages reported with ErsRep are written directly to the user standard Error output, not stored.

Language

Call

(ErsTaskIdType) = ErsStart (outRoutine, outArg, logRoutine, logArg, status)

Parameters

(">" input, "!" modified, "W" workspace, "<" output)

>	outRoutine	ErsOutRoutineType	If non zero, this routine will be called to output any messages output by ErsFlush.
>	outArg	void `*`	Passed directly to outRoutine as its first argument and not examined by Ers.
>	logRoutine	ErsLogRoutineType	If non zero, this routine will be called to log any messages reported by ErsRep.
>	logArg	void `*`	Passed directly to logRoutine as its first argument and not examined by Ers.
`!`	status	StatusType `*`	Modified status. routine returns immediately if non-zero. If Ers is already active, it is set to `ERS__ACTIVE`. An error allocating space for the table will set status to `ERS__MALLOCERR`. Under VxWorks, an error setting up a task varable will cause it to be set to `ERS__TASKVARERR`.
