Data Types, Header Files, and Libraries

To use the programming interfaces described in this chapter, you need the following header file.

#include <tsix/t6attrs.h>

The examples in this chapter compile with the following libraries:

-lsocket -lt6 -ltsol

Attribute Structure

The t6attr_t data structure can hold the full set security attributes.

Attribute Enumerations

The t6attr_id_t structure contains enumerated constants that represent the full set of security attribute values. Variables of type t6attr_t are initialized with these constants. Most of the constants have a fixed size in bytes as shown below; however, T6_GROUPS, has a variable size that reflects the actual size of its value.

• The t6set_attr(3NSL) routine takes a parameter of any type that must be cast to the appropriate type shown below.

• The t6get_attr(3NSL) routine returns a variable of any type that must be cast to the appropriate type shown below.

Attribute Mask

The t6mask_t data structure represents the set of security attributes of current interest. A variable of type t6mask_t is initialized by assigning the following enumerated values.
