PetscBagCreate

 Create a bag of values

Synopsis

#include "petscbag.h"   
PetscErrorCode PetscBagCreate(MPI_Comm comm, size_t bagsize, PetscBag *bag)
Collective

Input Parameters

comm - communicator to share bag
bagsize - size of the C structure holding the values

Output Parameter

bag - the bag of values

Notes

The size of the A struct must be small enough to fit in a PetscInt; by default PetscInt is 4 bytes; this means a bag cannot be larger than 2 gigabytes in length. The warning about casting to a shorter length can be ignored below unless your A struct is too large
