GSS_INQUIRE_CRED_BY_MECH(3)   Programmer's Manual  GSS_INQUIRE_CRED_BY_MECH(3)

NAME
     gss_inquire_cred_by_mech -- Obtain	per-mechanism information about	a cre-
     dential

SYNOPSIS
     #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);

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.	 Spec-
			 ify GSS_C_NO_CREDENTIAL to inquire about the default
			 initiator principal.

     mech_type		 The mechanism for which information should be re-
			 turned.

     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	cre-
			 dential usage for this	mechanism is GSS_C_ACCEPT,
			 this parameter	will be	set to zero.  If the implemen-
			 tation	does not support expiration of initiator cre-
			 dentials, the value GSS_C_INDEFINITE will be re-
			 turned.  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 creden-
			 tial 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 ac-
				 cessed

     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.
