Detailed Description

CK_SESSION_INFO; CK_SESSION_INFO_PTR

CK_SESSION_INFO provides information about a session. It is defined as follows:

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 12, Session Information Flags

Bit Flag	Mask	Meaning
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 should always be set to true

CK_SESSION_INFO_PTR is a pointer to a CK_SESSION_INFO.
