Instead, if ierr is nonzero it calls the PETSc error handler 590 and then immediately calls `MPI_Abort()`. It can therefore be used anywhere. 591 592 As per `MPI_Abort()` semantics the communicator passed must be valid, although there is currently 593 no attempt made at handling any potential errors from `MPI_Abort()`. Note that while 594 `MPI_Abort()` is required to terminate only those processes which reside on comm, it is often 595 the case that `MPI_Abort()` terminates *all* processes. 596 597 Example Usage: 598 .vb 599 PetscErrorCode boom(void) { return PETSC_ERR_MEM; } 600 601 void foo(void) 602 { 603 PetscCallAbort(PETSC_COMM_WORLD,boom()); // OK, does not return a type 604 } 605 606 double bar(void) 607 { 608 PetscCallAbort(PETSC_COMM_WORLD,boom()); // OK, does not return a type 609 } 610 611 PetscCallAbort(MPI_COMM_NULL,boom()); // ERROR, communicator should be valid 612 613 struct baz 614 { 615 baz() 616 { 617 PetscCallAbort(PETSC_COMM_SELF,boom()); // OK 618 } 619 620 ~baz() 621 { 622 PetscCallAbort(PETSC_COMM_SELF,boom()); // OK (in fact the only way to handle PETSc errors) 623 } 624 }; 625 .ve 626 627 Level: intermediate 628 629 .seealso: `SETERRABORT()`, `PetscTraceBackErrorHandler()`, `PetscPushErrorHandler()`, `PetscError()`, 630 `SETERRQ()`, `CHKMEMQ`, `PetscCallMPI()` 631 M*/ 632 #if defined(PETSC_CLANG_STATIC_ANALYZER) 633 void PetscCallAbort(MPI_Comm, PetscErrorCode); 634 void PetscCallContinue(PetscErrorCode); 635 #else 636 #define PetscCallAbort(comm, ...) \ 637 do { \ 638 PetscErrorCode ierr_abort_ = __VA_ARGS__; \ 639 if (PetscUnlikely(ierr_abort_)) { \ 640 PetscError(PETSC_COMM_SELF, __LINE__, PETSC_FUNCTION_NAME, __FILE__, ierr_abort_, PETSC_ERROR_REPEAT, " "); \ 641 MPI_Abort(comm, ierr_abort_); \ 642 } \ 643 } while (0) 644 #define PetscCallContinue(...) \ 645 do { \ 646 PetscErrorCode ierr_continue_ = __VA_ARGS__; \ 647 if (PetscUnlikely(ierr_continue_)) PetscError(PETSC_COMM_SELF, __LINE__, PETSC_FUNCTION_NAME, __FILE__, ierr_continue_, PETSC_ERROR_REPEAT, " "); \ 648 } while (0) 649 #endif 650 651 /*MC 652 CHKERRABORT - Checks error code returned from PETSc function.
