+~~~~~~~~~~~~~~~~
+

+
+   FC_GetSessionInfo - obtain information about a session.

+
+   .. code::
+
+      CK_RV FC_GetSessionInfo(
+        CK_SESSION_HANDLE hSession,

+

+
+   ``hSession``
+      [in] the open session handle.
+   ``pInfo``
+      [out] pointer to the `CK_SESSION_INFO </en-US/CK_SESSION_INFO>`__ structure to be returned.
+
+`Description <#description>`__
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. container::
+
+   ``FC_GetSessionInfo`` obtains information about a session. A user may call ``FC_GetSessionInfo``
+   without logging into the token (to assume the NSS User role).
+
+   If the NSS cryptographic module is in the error state, ``FC_GetSessionInfo`` returns
+   ``CKR_DEVICE_ERROR``. Otherwise, it fills in the ``CK_SESSION_INFO`` structure with the following
+   information:
+
+   -  ``state``: the state of the session, i.e., no role is assumed, the User role is assumed, or
+      the Crypto Officer role is assumed
+   -  ``flags``: bit flags that define the type of session
+
+      -  ``CKF_RW_SESSION (0x00000002)``: true if the session is read/write; false if the session is
+         read-only.
+      -  ``CKF_SERIAL_SESSION (0x00000004)``: this flag is provided for backward compatibility and
+         is always set to true.
