PetscAbortErrorHandler#

Error handler that calls abort on error. This routine is very useful when running in the debugger, because the user can look directly at the stack frames and the variables where the error occurred

Synopsis#

#include "petscsys.h" 
PetscErrorCode PetscAbortErrorHandler(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)
fun - the function name of the calling routine
file - the file in which the error was detected (usually indicated by __FILE__ in the calling routine)
mess - an error text string, usually this is 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 Keys#

-on_error_abort - Activates aborting when an error is encountered
-start_in_debugger [noxterm,lldb or gdb] [- display name] - Starts all processes in the debugger and uses PetscAbortErrorHandler(). By default on Linux the debugger is gdb and on macOS it is lldb

Notes#

Users do not directly employ this routine

Use PetscPushErrorHandler() to set the desired error handler. The currently available PETSc error handlers include PetscTraceBackErrorHandler(), PetscAttachDebuggerErrorHandler(), and PetscAbortErrorHandler().
