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_INITIALindicates this is the first time the error handler is being called while- PETSC_ERROR_REPEATindicates 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.
