1.1 General Attributes

1.1.1 XSI Option Groups

Question 1: Which of the following XSI Option Groups are supported by the implementation?

Response

Encryption	Yes
Realtime	No
Advanced Realtime	No
Realtime Threads	No
Advanced Realtime Threads	No
Tracing	No
XSI STREAMS	Yes
Legacy	No

Support for an XSI Option Group can only be claimed if all interfaces in that group behave according to the relevant descriptions in System Interfaces, Issue 6.

If an implementation does not support an Option Group then the system need not support the functions or functional behavior.

1.1.2 Options

Question 2: Which of the following options are supported by the implementation?

Response

IEC 60559 Floating-Point option	No
IPV6	Yes
Raw Sockets	Yes

Support for these options enables additional semantics for interfaces as described in the relevant descriptions in System Interfaces, Issue 6.

1.1.3 POSIX.1 Supported Features

Question 3: For each of the symbolic constants, specified in the <unistd.h> header file, are the associated features always available on the system?

Response

Macro Name	Meaning	Provided
_POSIX_CHOWN_RESTRICTED	The use of chown() is restricted to a process with appropriate privileges, and to changing the group ID of a file only to the effective group ID of the process or one of its supplementary group IDs.	Yes
_POSIX_NO_TRUNC	Pathname components longer than {NAME_MAX) generate an error.	Yes
