Legend

Good. A cell is good if the declaration is present in the header and can be linked with libc. This outcome means the test succeeded with the appropriate -D_POSIX_C_SOURCE=202405 or -D_XOPEN_SOURCE=800 feature macros and the standard libraries libc, libpthread, libm, librt, and libxnet.

Missing optional. A cell is missing_optional if the test could not be compiled, but the declaration is optional in POSIX and need not be provided.

Outside libc. A cell is outside_libc if the test could be compiled, but had to be linked with another standard library than the ones prescribed by POSIX: libc, libpthread, libm, librt, and libxnet. This may not conform to POSIX depending on the linking options provided by getconf(1)/confstr(3).

Extension. A cell is extension if the test could not be compiled with the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros, but it could instead be compiled with other system-specific feature macros that provide the entire API. This outcome means the system header feature macro logic does not support the latest POSIX.1-2024 standard and only receives partial credit. This outcome typically indicates a declaration new to POSIX.1-2024.

Previous posix. A cell is previous_posix if the test could not be compiled with the -D_POSIX_C_SOURCE=202405 or -D_XOPEN_SOURCE=800 feature macros from the POSIX.1-2024 standard, but the test could instead be compiled with the older -D_POSIX_C_SOURCE=200809L or -D_XOPEN_SOURCE=700 feature macros from the older POSIX.1-2008 standard. This outcome means the system header feature macro logic does not support the latest POSIX.1-2024 standard and only receives partial credit. In particular, the header did not check if the value was higher than the supported value, but instead hard-coded the supported values, and failed to be forward compatible with new standard versions.

None. A cell is none if there is no test data result for that operating system.

Compile error. A cell is compile_error if the test could not be compiled and the error message was not recognized as a more precise error test outcome.

Incompatible. A cell is incompatible if the declaration existed in the header, but had a signature that is incompatible with the standardized declaration. This outcome typically indicates a type error in the declaration. Addressing the issue may require an incompatible ABI change or special compatibility logic.

Missing header. A cell is missing_header if the header did not exist.

Undeclared. A cell is undeclared if the header did not contain the declaration.

Undefined reference. A cell is undefined if the test could be compiled, but could not be linked with the standard library.

Unknown type. A cell is unknown_type if the test could not be compiled and failed because a required type was not declared. In some cases, functions fail because the header omitted a required type for a function and instead declared the function in an alternate fashion with an incompatible alias for the type.
