   Input Parameters:

- message - Error message in the `printf()` format

  Level: beginner

  Notes:
  Enabled in both optimized and debug builds.

  As a general rule, `PetscCheck()` is used to check "usage error" (for example, passing an incorrect value as a function argument),
  `PetscAssert()` is used to "check for bugs in PETSc" (for example, is a value in a PETSc data structure nonsensical).
  However, for functions that are called in a "hot spot", for example, thousands of times in a loop, `PetscAssert()` should be used instead
  of `PetscCheck()` since the former is compiled out in PETSc's optimization code.

  Calls `SETERRQ()` if the assertion fails, so can only be called from functions returning a
  `PetscErrorCode` (or equivalent type after conversion).

/*MC
  PetscCall - Calls a PETSc function and then checks the resulting error code, if it is
  non-zero it calls the error handler and returns from the current function with the error
  code.

  Synopsis:
  #include <petscerror.h>
  void PetscCall(PetscFunction(args))

  Not Collective

  Input Parameter:
. PetscFunction - any PETSc function that returns an error code

  Level: beginner

  Notes:
  Once the error handler is called the calling function is then returned from with the given
  error code. Experienced users can set the error handler with `PetscPushErrorHandler()`.

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

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

  struct my_struct
  {
    void *data;
  } my_complex_type;

  struct my_struct bar(void)
  {
    PetscCall(foo(15)); // ERROR PetscErrorCode not convertible to struct my_struct!
  }

  PetscCall(bar()) // ERROR input not convertible to PetscErrorCode
.ve

  It is also possible to call this directly on a `PetscErrorCode` variable
.vb
  PetscCall(ierr);  // check if ierr is nonzero
.ve

  Should not be used to call callback functions provided by users, `PetscCallBack()` should be used in that situation.

  `PetscUseTypeMethod()` or `PetscTryTypeMethod()` should be used when calling functions pointers contained in a PETSc object's `ops` array

  Fortran Notes:
    The Fortran function in which this is used must declare a `PetscErrorCode` variable necessarily named `ierr`, and `ierr` must be
    the final argument to the PETSc function being called.

    In the main program and in Fortran subroutines that do not have `ierr` as the final return parameter, one
    should use `PetscCallA()`

  Example Fortran Usage:
.vb
  PetscErrorCode ierr
  Vec v

  ...
  PetscCall(VecShift(v, 1.0, ierr))
  PetscCallA(VecShift(v, 1.0, ierr))

- PetscFunction - user provided callback function that returns an error code

  Example Usage:
.vb

.ve

  Level: developer

  Notes:
  `PetscUseTypeMethod()` and ` PetscTryTypeMethod()` are the preferred API for this functionality. But when the callback functions are associated with a
  `DMSNES` or `DMTS` this API must be used.

  Once the error handler is called the calling function is then returned from with the given
  error code. Experienced users can set the error handler with `PetscPushErrorHandler()`.

  `PetscCallBack()` should only be called in PETSc when a call is being made to a user provided call-back routine.

  Developer Note:
  It would be good to provide a new API for when the callbacks are associated with `DMSNES` or `DMTS` so this routine could be used less

  Notes:
  Has identical usage to `PetscCall()`, except that it returns `void` on error instead of a
  `PetscErrorCode`. See `PetscCall()` for more detailed discussion.

  Note that users should prefer `PetscCallAbort()` to this routine. While this routine does
  "handle" errors by returning from the enclosing function, it effectively gobbles the
  error. Since the enclosing function itself returns `void`, its callers have no way of knowing
  that the routine returned early due to an error. `PetscCallAbort()` at least ensures that the
  program crashes gracefully.

  Synopsis:

  Collective

  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

  Level: intermediate

  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
  }

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

  PetscCallAbort(MPI_COMM_NULL,boom()); // ERROR, communicator should be valid

  struct baz
  {
    baz()
    {
      PetscCallAbort(PETSC_COMM_SELF,boom()); // OK

   PETSCABORT - Call `MPI_Abort()` with an informative error code

   Synopsis:

   Input Parameters:
+  comm - An MPI 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:
   If the option `-start_in_debugger` was used then this calls `abort()` to stop the program in the debugger.

   if `PetscCIEnabledPortableErrorOutput` is set, which means the code is running in the PETSc test harness (make test),
   and `comm` is `MPI_COMM_WORLD` it strives to exit cleanly without calling `MPI_Abort()` and instead calling `MPI_Finalize()`.

   This is currently only used when an error propagates up to the C `main()` program and is detected by a `PetscCall()`, `PetscCallMPI()`,
   or is set in `main()` with `SETERRQ()`. Abort calls such as `SETERRABORT()`,
   `PetscCheckAbort()`, `PetscCallMPIAbort()`, and `PetscCallAbort()` always call `MPI_Abort()` and do not have any special
   handling for the test harness.

   Developer Note:
   Should the other abort calls also pass through this call instead of calling `MPI_Abort()` directly?

  Notes:
  This macro may be used to check C++ expressions for exceptions in cases where you cannot

  instead.

   Not Collective; No Fortran Support

   Level: beginner

   Notes:
   This routine is a macro, so while it does not "return" anything itself, it does return from
   the function in the literal sense.

   Usually the return value is the integer literal `0` (for example in any function returning
   `PetscErrorCode`), however it is possible to return any arbitrary type. The arguments of
   this macro are placed before the `return` statement as-is.

   Any routine which returns via `PetscFunctionReturn()` must begin with a corresponding
   `PetscFunctionBegin`.

   For routines which return `void` use `PetscFunctionReturnVoid()` instead.

   Example Usage:
.vb
   PetscErrorCode foo(int *x)
   {
     PetscFunctionBegin; // don't forget the begin!
     *x = 10;
     PetscFunctionReturn(PETSC_SUCCESS);
