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 = 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.
