Product registration applies to software products operating in a specific hardware or hardware/software
environment.
A product may be registered either as a single product on a single
hardware configuration, known as Platform Specific Certification, or as a family of
binary-compatible products on a range of hardware, known as Product Family Certification. In the former case registration is on the basis of a single test
report, in the latter two test reports from distinct members of the
binary-compatible family are required.
Enter the level of Certification, either "Platform Specific Certification" or "Product Family Certification". If Product Family Certification then enter a full description below of the binary-compatible family
| Level of Certification | Binary-compatible Family |
|---|---|
| Enter_Certification_Level |
Enter the precise hardware/software environment(s) tested and test suite and version number. If Product Family Certification then two testing environments should be entered below.

Question 1: Are the required features below supported for all system configurations?
Response
Where indicated in the following table, enter one of the options given (either "Yes" or "Variable"). Enter "Variable" if there are system dependent or file_system dependent configuration procedures that can remove or modify any or all of these features.
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. Enter_Yes_or_Variable _POSIX_NO_TRUNC Pathname components longer than {NAME_MAX) generate an error. Enter_Yes_or_Variable
If one of the above is Variable, describe in the area below the manner in which variations occur.
Rationale
Although all implementations conforming to IEEE Std 1003.1-2001 support the features described above, there may be system-dependent or file system-dependent configuration procedures that can remove or modify any or all of these features. Such configurations should not be made if strict compliance is required.

Question 4: What are the values associated with the following constants (optionally specified in the <limits.h> header file)?
Response
For the lines in the table below, add the minimum and maximum values for your implementation. This value may be stated to be "Unlimited" if your implementation does not impose a limit. The minimum should be the smallest value that is returned from sysconf() or pathconf(), or as defined in <limits.h>. The maximum value should be the largest value that is returned from sysconf() or pathconf().

Enter_minimum Enter_maximum CHILD_MAX Maximum number of processes per user ID. Enter_minimum Enter_maximum FILESIZEBITS Minimum number of bits needed to represent as a signed integer value the maximum size of a regular file.

Question 5: What are the values associated with the following constant specified in the <limits.h> header file?
Response
For the line in the table below, add the minimum and maximum values for your implementation. This value may be stated to be "Unlimited" if your implementation does not impose a limit. The minimum should be the smallest value that is returned from sysconf(), or as defined in <limits.h>. The maximum value should be the largest value that is returned from sysconf().
Macro Name Meaning Minimum Maximum NGROUPS_MAX Maximum number of simultaneous supplementary group IDs per process. Enter_minimum Enter_maximum
Rationale
This limit can vary within bounds set by the Base Definitions Volume. The minimum value that a limit can take on any conforming system is given in the corresponding _POSIX_ value. A specific conforming implementation may provide a higher minimum value than this and the maximum value that it provides can differ from the minimum. Some conforming implementations may provide a potentially infinite value as the maximum, in which case the value is considered to be indeterminate. The minimum value must always be definitive since the _POSIX_ value provides a known lower bound for the range of possible values.

IEEE Std 1003.1, 2003 Edition, the System Interfaces Volume, Chapter 3, System Interfaces, feholdexcept().
Question 13: Which file types (regular, directory, FIFO, special and so on) are considered to be executable?
Response
Enter the file types that are executable on your implementation in the area below.
Rationale
The EACCES error associated with exec functions occurs in circumstances when the implementation does not support execution of files of the type specified. A list of these file types needs to be provided.
Reference
IEEE Std 1003.1, 2003 Edition, the System Interfaces Volume, Chapter 3, System Interfaces, exec.
Question 14: What file access control mechanisms does the implementation provide?
Response
Either indicate that "Standard access control is provided.", that the reader should "Refer to the POSIX Conformance Document", or provide a detailed description of the access control mechanisms on your implementation.
Rationale
the System Interfaces Volume notes that implementations may provide additional or alternate file access control mechanisms, or both.
Reference
IEEE Std 1003.1, 2003 Edition, The Base Definitions Volume, Chapter 4, General Concepts, Section 4.4, File Access Permissions.
Question 15: Are any additional or alternate file access control mechanisms implemented that could cause fstat() or stat() to fail?
Response
Enter_Yes_or_No
If you answered Yes above, Either indicate below that the reader should "Refer to the POSIX Conformance Document", or provide a detailed description of the additional or alternate access mechanisms on your implementation that would cause fstat() or stat() to fail.
Rationale
the System Interfaces Volume notes that there could be an interaction between additional and alternate access controls and the success of fstat() and stat(). This would suggest that an implementation can allow access to a file but not allow the process to gain information about the status of the file.

Question 16: What coded character sets are supported by the implementation?
Response
Enter your response in the area below:
Rationale
The Base Definitions Volume states that conforming implementations support one or more coded character sets, and that each of these includes the portable character set.
Reference
IEEE Std 1003.1, 2003 Edition, The Base Definitions Volume, Chapter 6, Character Set.
Question 17: What is the implementation's underlying internal codeset?
Response
If the implementation does not use ISO 8859-1:1987, provide the name or description of the underlying codeset. If the implementation does use ISO 8859-1:1987, just enter "ISO 8859-1:1987" below.
Rationale
It is useful to be aware of the underlying codeset of the implementation.

Question 18: What is the limit the implementation places on the length of a socket's listen queue?
Response
Indicate the implementation's limit on the length of the socket's listen queue, or "None" if no limit is imposed.
Rationale
The specification states that an implementation may limit the length of a socket's listen queue, and that this limit may be imposed if the setting of the backlog argument exceeds an implementation-defined maximum value.
Reference
IEEE Std 1003.1, 2003 Edition, the System Interfaces Volume, Chapter 3, listen().
Question 19: What combinations of address family, socket types, and protocols does the implementation support?
Response
Indicate the supported combinations below , "N/A" equals not applicable.
Address Family Protocol Socket Type Supported? AF_UNIX N/A STREAM Enter_Yes_or_No AF_UNIX N/A SEQPACKET Enter_Yes_or_No AF_UNIX N/A DGRAM Enter_Yes_or_No AF_INET TCP STREAM Enter_Yes_or_No AF_INET UDP DGRAM Enter_Yes_or_No AF_INET6 TCP STREAM Enter_Yes_or_No AF_INET6 UDP DGRAM Enter_Yes_or_No
If any additional combinations are supported please list them below.
Rationale
The specification states that the domains, socket types and protocols supported by a conforming system are implementation-defined. The 1003.1-2003 System Interfaces Product Standard states that conforming products shall be available in configurations that support at least following socket domains:
- AF_INET, with at least SOCK_STREAM and SOCK_DGRAM socket types
- AF_UNIX, with at least the SOCK_STREAM socket type.

Question 20: What Socket Types does the implementation support?
Response
List the supported types.
Rationale
The specification states that there are four socket types defined - SOCK_RAW, SOCK_STREAM, SOCK_SEQPACKET and SOCK_DGRAM - but does not state which are required. Implementations may also support additional socket types.

Question 21: What C-language compilation environments are provided?
Response
Programming Environment Provided The implementation provides a C-language compilation environment with
32-bit int, long, pointer and off_t types.Enter_Yes_or_No The implementation provides a C-language compilation environment with
32-bit int, long and pointer types and an off_t type using at least 64 bits.Enter_Yes_or_No The implementation provides a C-language compilation environment with
32-bit int, and 64-bit long, pointer and off_t types.Enter_Yes_or_No The implementation provides a C-language compilation environment with
int using at least 32-bits, and long, pointer and off_t types using at least 64 bits.Enter_Yes_or_No
Rationale
The Base Definitions Volume defines these scenarios as possible C-language compilation environment offerings.
Reference
IEEE Std 1003.1, 2003 Edition, The Base Definitions Volume, Chapter 13, Headers, <unistd.h>.
Question 22: What execution environments are provided on the system under test?
Response
Execution Environment Provided The implementation provides an execution environment with
32-bit int, long, pointer and off_t types.Enter_Yes_or_No The implementation provides an execution environment with
32-bit int, long and pointer types and an off_t type using at least 64 bits.Enter_Yes_or_No The implementation provides an execution environment with
32-bit int, and 64-bit long, pointer and off_t types.Enter_Yes_or_No The implementation provides an execution environment with
int using at least 32-bits, and long, pointer and off_t types using at least 64 bits.Enter_Yes_or_No
Rationale
The Base Definitions Volume defines four scenarios as possible C-language compilation environment offerings but does not define which corresponding execution environments are supported.
