PetscEmacsClientErrorHandler

Error handler that uses the emacsclient program to load the file where the error occurred. 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, No Fortran Support

Input Parameters

• comm - communicator over which error occurred

• line - the line number of the error (usually indicated by __LINE__ in the calling routine)

• file - the file in which the error was detected (usually indicated by __FILE__ in the calling routine)

• fun - the function name of the calling routine

• mess - an error text string, usually just printed to the screen

• n - the generic error number

• p - PETSC_ERROR_INITIAL indicates this is the first time the error handler is being called while PETSC_ERROR_REPEAT indicates it was previously called

• ctx - error handler context

Options Database Key

• -on_error_emacs - will contact machinename to open the Emacs client there

Note

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

Developer Note

Since this is an error handler it cannot call PetscCall(); thus we just return if an error is detected. But some of the functions it calls do perform error checking that may not be appropriate in a error handler call.
