## Synopsis
```
#include "petscsys.h"   
PetscErrorCode PetscOptionsGetBoolArray(PetscOptions options, const char pre[], const char name[], PetscBool dvalue[], PetscInt *nmax, PetscBool *set)
```
Not Collective


## Input Parameters

- ***options -*** options database, use `NULL` for default global database
- ***pre -*** string to prepend to each name or `NULL`
- ***name -*** the option one is seeking



## Output Parameters

- ***dvalue -*** the integer values to return
- ***nmax -*** On input maximum number of values to retrieve, on output the actual number of values retrieved
- ***set -*** `PETSC_TRUE` if found, else `PETSC_FALSE`





## Note
TRUE, true, YES, yes, nostring, and 1 all translate to `PETSC_TRUE`. FALSE, false, NO, no, and 0 all translate to `PETSC_FALSE`
