# shz_xmtrx_init_identity_safe

Source: https://sh4zam.com/api/xmtrx/shz_xmtrx_init_identity_safe/

```c
SHZ_INLINE void shz_xmtrx_init_identity_safe(void) SHZ_NOEXCEPT;
```

Safely initializes XMTRX to be a 4D identity matrix.

**Deprecated:** `shz_xmtrx_init_identity()` is already safe now by default. This routine simply calls directly into it and should not be used.

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `` | `void` |  |

## Returns

Nothing (`void`).
