## Implemented Interfaces

GckSession implements GInitable and GAsyncInitable.

## Description

Before performing any PKCS11 operations, a session must be opened. This is analogous to an open database handle, or a file handle.

## Functions

### gck_session_from_handle ()

    GckSession *
    gck_session_from_handle (GckSlot *slot,
                             gulong session_handle,
                             GckSessionOptions options);

Initialize a GckSession object from a raw PKCS#11 session handle. Usually one would use the `gck_slot_open_session()` function to create a session.

#### Parameters

slot | The slot which the session belongs to. |
session_handle | the raw PKCS#11 handle of the session |
options | Session options. Those which are used during opening a session have no effect. |

#### Returns

the new GckSession object.
