CK_TOKEN_INFO_PTR is a pointer to a CK_TOKEN_INFO.
8.3. Session typesCryptoki represents session information with the following types: CK_SESSION_HANDLE; CK_SESSION_HANDLE_PTRCK_SESSION_HANDLE is a Cryptoki-assigned value that identifies a session. It is defined as follows: typedef CK_ULONG CK_SESSION_HANDLE; Valid session handles in Cryptoki always have nonzero values. For developers’ convenience, Cryptoki defines the following symbolic value: #define CK_INVALID_HANDLE 0 CK_SESSION_HANDLE_PTR is a pointer to a CK_SESSION_HANDLE. CK_USER_TYPECK_USER_TYPE holds the types of Cryptoki users described in Section . It is defined as follows: typedef CK_ULONG CK_USER_TYPE; For this version of Cryptoki, the following types of users are defined: #define CKU_SO 0 #define CKU_USER 1 CK_STATECK_STATE holds the session state, as described in Sections and . It is defined as follows: typedef CK_ULONG CK_STATE; For this version of Cryptoki, the following session states are defined: #define CKS_RO_PUBLIC_SESSION 0 #define CKS_RO_USER_FUNCTIONS 1 #define CKS_RW_PUBLIC_SESSION 2 #define CKS_RW_USER_FUNCTIONS 3 #define CKS_RW_SO_FUNCTIONS 4 CK_SESSION_INFO; CK_SESSION_INFO_PTRCK_SESSION_INFO provides information about a session. It is defined as follows: typedef struct CK_SESSION_INFO { CK_SLOT_ID slotID; CK_STATE state; CK_FLAGS flags; CK_ULONG ulDeviceError; } CK_SESSION_INFO; The fields of the structure have the following meanings: slotID ID of the slot that interfaces with the token state the state of the session flags bit flags that define the type of session; the flags are defined below ulDeviceError an error code defined by the cryptographic device. Used for errors not covered by Cryptoki. The following table defines the flags field: Table 11, Session Information Flags
