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.  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 ini‐
		   tiate contexts, or if the credential usage for this mecha‐
		   nism is GSS_C_ACCEPT, this parameter will be set to zero.
		   If the implementation does not support expiration of ini‐
		   tiator 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 mecha‐
		   nism is GSS_C_INITIATE, this parameter will be set to zero.
		   If the implementation does not support expiration of accep‐
		   tor 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 mecha‐
		   nism.  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.
