# DMPlexGetPointGlobalField
get location of point field data in global `Vec` 
## Synopsis
```
#include "petscdmplex.h"   
PetscErrorCode DMPlexGetPointGlobalField(DM dm, PetscInt point, PetscInt field, PetscInt *start, PetscInt *end)
```
Not Collective


## Input Parameters

- ***dm -*** `DM` defining the topological space
- ***point -*** topological point
- ***field -*** the field number



## Output Parameters

- ***start -*** start of point data; returns -(globalStart+1) if point is not owned
- ***end -*** end of point data; returns -(globalEnd+1) if point is not owned





## Note
This is a half open interval [start, end)
