Description: Reference for Gm.device_tree_get_compatibles

### Function

# Gmdevice_tree_get_compatibles

since: 0.0.1

#### Declaration [src]

    GStrv
    gm_device_tree_get_compatibles (
      const char* sysfs_root,
      GError** error
    )

#### Description [src]

Read compatible machine types from `sysfs_root/firmware/devicetree/base/compatible` on Linux. If the path doesn’t exist or host is not Linux return `NULL`.

For debugging purposes `GMOBILE_DT_COMPATIBLES` can be set to a `:` separated list of compatibles which will be returned instead.

Available since: 0.0.1

#### Parameters

`sysfs_root`

  Type: `const char*`

  Path where /sys is mounted. Defaults to `/sys` if `NULL` is passed.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: An array of `utf8`

Compatible machine types or `NULL`.

The array is `NULL`-terminated.
Each element is a NUL terminated UTF-8 string.
