5: PetscMPIAbortErrorHandler - Calls PETSCABORT and exits.
7: Not Collective
9: Input Parameters:
10: + comm - communicator over which error occurred
11: . line - the line number of the error (indicated by __LINE__)
12: . file - the file in which the error was detected (indicated by __FILE__)
13: . mess - an error text string, usually just printed to the screen
14: . n - the generic error number
15: . p - PETSC_ERROR_INITIAL if error just detected, otherwise PETSC_ERROR_REPEAT
16: - ctx - error handler context
18: Level: developer
20: Notes:
21: Most users need not directly employ this routine and the other error
22: handlers, but can instead use the simplified interface SETERRQ, which has
23: the calling sequence
24: $ SETERRQ(comm,n,p,mess)
26: Notes for experienced users:
27: Use PetscPushErrorHandler() to set the desired error handler. The
28: currently available PETSc error handlers include PetscTraceBackErrorHandler(),
29: PetscMPIAbortErrorHandler(), PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler().
31: .seealso: PetscPushErrorHandler(), PetscAttachDebuggerErrorHandler(),
32: PetscAbortErrorHandler(), PetscTraceBackErrorHandler()
