| ## NAME |
| |
| <!-- Updated by update-docs-from-fidl, do not edit. --> |
| |
| Get supported hardware capabilities. |
| |
| ## SYNOPSIS |
| |
| <!-- Updated by update-docs-from-fidl, do not edit. --> |
| |
| ```c |
| #include <zircon/syscalls.h> |
| |
| zx_status_t zx_system_get_features(uint32_t kind, uint32_t* features); |
| ``` |
| |
| ## DESCRIPTION |
| |
| `zx_system_get_features()` populates *features* with a bit mask of |
| hardware-specific features. *kind* indicates the specific type of features |
| to retrieve, e.g. **ZX_FEATURE_KIND_CPU**. The supported kinds and the meaning |
| of individual feature bits is hardware-dependent. |
| |

| |
| ## RETURN VALUE |
| |
| `zx_system_get_features()` returns **ZX_OK** on success. |
| |
| ## ERRORS |
| |
| **ZX_ERR_NOT_SUPPORTED** The requested feature kind is not available on this |
| platform. |
| |
