DESCRIPTION

Obtains per-mechanism information about a credential.

PARAMETERS

minor_status Mechanism specific status code.
cred_handle A handle that refers to the target credential. Specify GSS_C_NO_CREDENTIAL to inquire about the default initiator principal.
mech_type The mechanism for which information should be returned.
name The name whose identity the credential asserts. Storage associated with this name must be freed by the application after use with a call to gss_release_name. Specify NULL if not required.
initiator_lifetime
  The number of seconds for which the credential will remain capable of initiating security contexts under the specified mechanism. If the credential can no longer be used to initiate contexts, or if the credential usage for this mechanism is GSS_C_ACCEPT, this parameter will be set to zero. If the implementation does not support expiration of initiator credentials, the value GSS_C_INDEFINITE will be returned. Specify NULL if not required.
acceptor_lifetime The number of seconds for which the credential will remain capable of accepting security contexts under the specified mechanism. If the credential can no longer be used to accept contexts, or if the credential usage for this mechanism is GSS_C_INITIATE, this parameter will be set to zero. If the implementation does not support expiration of acceptor credentials, the value GSS_C_INDEFINITE will be returned. Specify NULL if not required.
cred_usage How the credential may be used with the specified mechanism. One of the following:
GSS_C_INITIATE
GSS_C_ACCEPT
GSS_C_BOTH
Specify NULL if not required.

RETURN VALUES

GSS_S_COMPLETE Successful completion
GSS_S_NO_CRED The referenced credentials could not be accessed
GSS_S_DEFECTIVE_CREDENTIAL
  The referenced credentials were invalid
GSS_S_CREDENTIALS_EXPIRED The referenced credentials have expired. If the lifetime parameter was not passed as NULL, it will be set to 0.
