## Description

A OstreeSePolicy object can load the SELinux policy from a given root and perform labeling.

## Functions

### ostree_sepolicy_new ()

    OstreeSePolicy *
    ostree_sepolicy_new (GFile *path,
                         GCancellable *cancellable,
                         GError **error);

#### Parameters

path | Path to a root directory |
cancellable | Cancellable |
error | Error |

#### Returns

An accessor object for SELinux policy in root located at `path` .

[transfer full]

### ostree_sepolicy_new_at ()

    OstreeSePolicy *
    ostree_sepolicy_new_at (int rootfs_dfd,
                            GCancellable *cancellable,
                            GError **error);

#### Parameters

rootfs_dfd | Directory fd for rootfs (will not be cloned) |
cancellable | Cancellable |
error | Error |

#### Returns

An accessor object for SELinux policy in root located at `rootfs_dfd` .

[transfer full]

Since: 2017.4

### ostree_sepolicy_get_path ()

    GFile *
    ostree_sepolicy_get_path (OstreeSePolicy *self);

#### Returns

Path to rootfs.

[transfer none]

### ostree_sepolicy_get_name ()

    const char *
    ostree_sepolicy_get_name (OstreeSePolicy *self);

#### Returns

Type of current policy.

[transfer none]

### ostree_sepolicy_get_label ()

    gboolean
    ostree_sepolicy_get_label (OstreeSePolicy *self,
                               const char *relpath,
                               guint32 unix_mode,
                               char **out_label,
                               GCancellable *cancellable,
                               GError **error);

Store in `out_label` the security context for the given `relpath` and mode `unix_mode` . If the policy does not specify a label, `NULL` will be returned.

#### Parameters

self | Self |
relpath | Path |
unix_mode | Unix mode |
out_label | Return location for security context. | [allow-none][out][transfer full]
cancellable | Cancellable |
error | Error |
