PetscSegBufferGetInts

access an array of PetscInt from a PetscSegBuffer

Synopsis

#include <petscsys.h>
PetscErrorCode PetscSegBufferGetInts(PetscSegBuffer seg, size_t count, PetscInt *PETSC_RESTRICT *slot);

No Fortran Support

Input Parameters

• seg - PetscSegBuffer buffer

• count - number of entries needed

Output Parameter

• buf - address of new buffer for contiguous data

Developer Note

Type-safe wrapper to encourage use of PETSC_RESTRICT. Does not use PetscFunctionBegin because the error handling prevents the compiler from completely erasing the stub. This is called in inner loops so it has to be as fast as possible.
