NAME

       gss_inquire_cred_by_mech - API function

SYNOPSIS

       #include <gss.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);

ARGUMENTS

       OM_uint32 * minor_status
                   (Integer, modify) Mechanism specific status code.

       const gss_cred_id_t cred_handle
                   (gss_cred_id_t, read) A handle that refers to the
                     target credential.  Specify GSS_C_NO_CREDENTIAL to inquire about
                     the default initiator principal.

       const gss_OID mech_type
                   (gss_OID, read) The mechanism for which information
                    should be returned.

       gss_name_t * name
                   (gss_name_t, modify, optional) 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.

       OM_uint32 * initiator_lifetime
                   (Integer, modify, optional) 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.

       OM_uint32 * acceptor_lifetime
                   (Integer, modify, optional) 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.

       gss_cred_usage_t * cred_usage
                   (gss_cred_usage_t, modify, optional) 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.

DESCRIPTION

       Obtains per-mechanism information about a credential.

RETURN VALUE

       `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.
