# PetscQuadratureGetData
Returns the data defining the `PetscQuadrature` 
## Synopsis
```
#include "petscdt.h" 
PetscErrorCode PetscQuadratureGetData(PetscQuadrature q, PetscInt *dim, PetscInt *Nc, PetscInt *npoints, const PetscReal *points[], const PetscReal *weights[])
```
Not collective


## Input Parameter

- ***q  -*** The `PetscQuadrature` object



## Output Parameters

- ***dim -*** The spatial dimension
- ***Nc -*** The number of components
- ***npoints -*** The number of quadrature points
- ***points -*** The coordinates of each quadrature point
- ***weights -*** The weight of each quadrature point





## Fortran Note
From Fortran you must call `PetscQuadratureRestoreData()` when you are done with the data
