# PetscStrToArray
Separates a string by a character (for example ' ' or '\n') and creates an array of strings
## Synopsis
```
#include "petscsys.h"
PetscErrorCode PetscStrToArray(const char s[], char sp, int *argc, char ***args)
```
Not Collective; No Fortran Support
## Input Parameters
- ***s -*** pointer to string
- ***sp -*** separator character
## Output Parameters
- ***argc -*** the number of entries in the array
- ***args -*** an array of the entries with a `NULL` at the end
## Note
This may be called before `PetscInitialize()` or after `PetscFinalize()`
## Developer Notes
Uses raw `malloc()` and does not call error handlers since this may be used before PETSc is initialized.
Used to generate argc, args arguments passed to `MPI_Init()`
