Extended PKCS #11 Functions: SUNW_C_GetMechSession()

SUNW_C_GetMechSession() is a convenience function that initializes the Solaris cryptographic framework. The function then starts a session with the specified mechanism. SUNW_C_GetMechSession() uses the following syntax:

SUNW_C_GetMechSession(CK_MECHANISM_TYPE mech, C\
K_SESSION_HANDLE_PTR hSession)

The mech parameter is used to specify the mechanism to be used. hSession is a pointer to the session location.

Internally, SUNW_C_GetMechSession() calls C_Initialize() to initialize the cryptoki library. SUNW_C_GetMechSession() next calls C_GetSlotList() and C_GetMechanismInfo() to search through the available slots for a token with the specified mechanism. When the mechanism is found, SUNW_C_GetMechSession() calls C_OpenSession() to open a session.

The SUNW_C_GetMechSession() only needs to be called once. However, calling SUNW_C_GetMechSession() multiple times does not cause any problems.
