463/*@C
464 DMStagVecSplitToDMDA - create a DMDA and Vec from a DMStag and Vec
465
466 Logically Collective
467
468 High-level helper function which accepts a DMStag, a global vector, and location/dof,
469 and generates a corresponding DMDA and Vec.
470
471 Input Parameters:
472+ dm - the DMStag object
473. vec- Vec object associated with dm
474. loc - which subgrid to extract (see DMStagStencilLocation)
475- c - which component to extract (see note below)
476
477 Output Parameters:
478+ pda - the new DMDA
479- pdavec - the new Vec
480
481 Notes:
482 If a c value of -k is provided, the first k dof for that position are extracted,
483 padding with zero values if needbe. If a non-negative value is provided, a single
484 dof is extracted.
485
486 The caller is responsible for destroying the created DMDA and Vec.
