C_GetOperationState() public méthode

Obtains a copy of the cryptographic operations state of a session encoded as byte array
public C_GetOperationState ( uint session, byte operationState, uint &operationStateLen ) : CKR
session uint The session's handle
operationState byte /// If set to null then the length of state is returned in "operationStateLen" parameter, without actually returning a state. /// If not set to null then "operationStateLen" parameter must contain the lenght of operationState array and state is returned in "operationState" parameter. ///
operationStateLen uint Location that receives the length in bytes of the state
