PetscEmacsClientErrorHandler

Error handler that uses the emacsclient program to load the file where the error occured. Then calls the "previous" error handler.

Synopsis

#include "petscsys.h" 
PetscErrorCode  PetscEmacsClientErrorHandler(MPI_Comm comm,int line,const char *fun,const char *file,PetscErrorCode n,PetscErrorType p,const char *mess,void *ctx)
Not Collective

Input Parameters

comm - communicator over which error occured
line - the line number of the error (indicated by __LINE__)
func - the function where error is detected (indicated by __FUNCT__)
file - the file in which the error was detected (indicated by __FILE__)
mess - an error text string, usually just printed to the screen
n - the generic error number
p - specific error number
ctx - error handler context

Options Database Key

-on_error_emacs <machinename> -

Notes

You must put (server-start) in your .emacs file for the emacsclient software to work

Most users need not directly employ this routine and the other error handlers, but can instead use the simplified interface SETERRQ, which has the calling sequence

    SETERRQ(PETSC_COMM_SELF,number,p,mess)

Notes for experienced users

Use PetscPushErrorHandler() to set the desired error handler.

Developer Note: Since this is an error handler it cannot call CHKERRQ(); thus we just return if an error is detected.
