PetscCallThrow#

Checks error code, if non-zero it calls the C++ error handler which throws an exception

Synopsis#

#include <petscerror.h>
void PetscCallThrow(PetscErrorCode ierr)

Not Collective

Input Parameter#

  • ierr - nonzero error code, see the list of standard error codes in include/petscerror.h

Notes#

Requires PETSc to be configured with clanguage of c++. Throws a std::runtime_error() on error.

Once the error handler throws the exception you can use PetscCallVoid() which returns without an error code (bad idea since the error is ignored) or PetscCallAbort() to have MPI_Abort() called immediately.
