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.
