### Input Parameters

| pre | - string to prepend to name or PETSC_NULL
| name | - the option one is seeking
| nmax | - maximum number of strings

### Output Parameter

| strings | - location to copy strings
| flg | - PETSC_TRUE if found, else PETSC_FALSE

### C++ variants

| PetscOptionsGetStringArray(const char b[],char *i[],PetscInt *ii,PetscTruth *f) |  | -> |  | PetscOptionsGetStringArray(PETSC_NULL,b,i,ii,f)
