64 *
65 * The =openpam_get_feature function stores the current state of the
66 * specified feature in the variable pointed to by its =onoff argument.
67 *
68 * The following features are recognized:
69 *
70 *	=OPENPAM_RESTRICT_SERVICE_NAME:
71 *		Disallow path separators in service names.
72 *		This feature is enabled by default.
73 *		Disabling it allows the application to specify the path to
74 *		the desired policy file directly.
75 *
76 *	=OPENPAM_VERIFY_POLICY_FILE:
77 *		Verify the ownership and permissions of the policy file
78 *		and the path leading up to it.
79 *		This feature is enabled by default.
80 *
81 *	=OPENPAM_RESTRICT_MODULE_NAME:
82 *		Disallow path separators in module names.
83 *		This feature is disabled by default.
84 *		Enabling it prevents the use of modules in non-standard
85 *		locations.
86 *
87 *	=OPENPAM_VERIFY_MODULE_FILE:
88 *		Verify the ownership and permissions of each loadable
89 *		module and the path leading up to it.
90 *		This feature is enabled by default.
