#include <gssapi/gssapi.h>

OM_uint32
gss_inquire_cred_by_mech(OM_uint32 *minor_status, const gss_cred_id_t cred_handle, const gss_OID mech_type, gss_name_t *name, OM_uint32 *initiator_lifetime, OM_uint32 *acceptor_lifetime, gss_cred_usage_t *cred_usage);

Obtains per-mechanism information about a credential.

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.

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.
