# PetscDeviceInitType
Initialization strategy for `PetscDevice` 
## Synopsis
```
#include <petscdevicetypes.h> 
typedef enum {
  PETSC_DEVICE_INIT_NONE,
  PETSC_DEVICE_INIT_LAZY,
  PETSC_DEVICE_INIT_EAGER
} PetscDeviceInitType;
```

## Values

- ***`PETSC_DEVICE_INIT_NONE`  -*** PetscDevice is never initialized
- ***`PETSC_DEVICE_INIT_LAZY`  -*** PetscDevice is initialized on demand
- ***`PETSC_DEVICE_INIT_EAGER` -*** PetscDevice is initialized as soon as possible





## Notes
`PETSC_DEVICE_INIT_NONE` implies that any initialization of `PetscDevice` is disallowed and
doing so results in an error. Useful to ensure that no accelerator is used in a program.


## See Also

`PetscDeviceInitialized()`, `PetscDeviceCreate()`
