# PetscOptionsStringArray
Gets an array of string values for a particular option in the database. The values must be separated with commas with no intervening spaces. Logically Collective on the communicator passed in `PetscOptionsBegin()`; No Fortran Support


## Synopsis
```
#include "petscsys.h"
PetscErrorCode PetscOptionsStringArray(const char opt[],const char text[],const char man[],char *value[],PetscInt *nmax,PetscBool  *set)
```

## Input Parameters

- ***opt -*** the option one is seeking
- ***text -*** short string describing option
- ***man -*** manual page for option
- ***nmax -*** maximum number of strings



## Output Parameters

- ***value -*** location to copy strings
- ***nmax -*** actual number of strings found
- ***set -*** `PETSC_TRUE` if found, else `PETSC_FALSE`





## Notes
The user should pass in an array of pointers to char, to hold all the
strings returned by this function.

The user is responsible for deallocating the strings that are
returned.

Must be between a `PetscOptionsBegin()` and a `PetscOptionsEnd()`
