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.
