  Synopsis:

  Notes:

  PetscCall() cannot be used in functions returning a datatype not convertable to
  PetscErrorCode. For example, PetscCall() may not be used in functions returning void, use
  PetscCallVoid() in this case.

  Fortran Notes:
  PetscCall() may be called from Fortran subroutines but CHKERRA() must be called from the
  Fortran main program.

  Example Usage:
.vb
  PetscCall(PetscInitiailize(...)); // OK to call even when PETSc is not yet initialized!

  extern int foo(int);

  PetscCall(foo(1)); // OK if int is convertable to PetscErrorCode

  Synopsis:

  void PetscCallAbort(MPI_Comm comm, PetscErrorCode ierr)

  Collective on comm

  Input Parameters:
+ comm - the MPI communicator on which to abort
- ierr - nonzero error code, see the list of standard error codes in include/petscerror.h

  Notes:
  This macro has identical type and usage semantics to PetscCall() with the important caveat
  that this macro does not return. Instead, if ierr is nonzero it calls the PETSc error handler
  and then immediately calls MPI_Abort(). It can therefore be used anywhere.

  As per MPI_Abort semantics the communicator passed must be valid, although there is currently
  no attempt made at handling any potential errors from MPI_Abort(). Note that while
  MPI_Abort() is required to terminate only those processes which reside on comm, it is often
  the case that MPI_Abort() terminates *all* processes.

  Example Usage:
.vb
  PetscErrorCode boom(void) { return PETSC_ERR_MEM; }

  void foo(void)
  {
    PetscCallAbort(PETSC_COMM_WORLD,boom()); // OK, does not return a type

      This should only be used with Fortran. With C/C++, use PetscCall() in normal usage,
      or PetscCallAbort() if wanting to abort immediately on error.

   Fortran Notes:
      PetscCall() may be called from Fortran subroutines but CHKERRA() must be called from the

   PETSCABORT - Call MPI_Abort with an informative error code

   Synopsis:
   #include <petscsys.h>
   PETSCABORT(MPI_Comm comm, PetscErrorCode ierr)

   Input Parameters:
+  comm - A communicator, so that the error can be collective
-  ierr - nonzero error code, see the list of standard error codes in include/petscerror.h

   Level: advanced

   Notes:
   We pass MPI_Abort() an error code of format XX_YYYY_ZZZ, where XX, YYYY are an index and line number of the file
   where PETSCABORT is called, respectively. ZZZ is the PETSc error code.

   If XX is zero, this means that the call was made in the routine main().
   If XX is one, that means 1) the file is not in PETSc (it may be in users code); OR 2) the file is in PETSc but PetscAbortSourceFiles[]
     is out of date. PETSc developers have to update it.
   Otherwise, look up the value of XX in the table PetscAbortSourceFiles[] in src/sys/error/err.c to map XX back to the source file where the PETSCABORT() was called.

   If the option -start_in_debugger was used then this calls abort() to stop the program in the debugger.
