#include "petscsys.h" PetscErrorCode PetscError(MPI_Comm comm,int line,const char *func,const char *file,PetscErrorCode n,PetscErrorType p,const char *mess,...)Not Collective
| comm | - communicator over which error occurred. ALL ranks of this communicator MUST call this routine | |
| line | - the line number of the error (indicated by __LINE__) | |
| func | - the function where the error occured (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 | - PETSC_ERROR_INITIAL indicates the error was initially detected, PETSC_ERROR_REPEAT indicates this is a traceback from a previously detected error | |
| mess | - formatted message string - aka printf |
SETERRQ(comm,n,mess)
Experienced users can set the error handler with PetscPushErrorHandler().
Developer Note: Since this is called after an error condition it should not be calling any error handlers (currently it ignores any error codes) BUT this routine does call regular PETSc functions that may call error handlers, this is problematic and could be fixed by never calling other PETSc routines but this annoying.
