Legend

Good. A cell is good if all declarations in the header are allowed per POSIX under the -D_POSIX_C_SOURCE=202405 or -D_XOPEN_SOURCE=800 feature macros, and each declaration had the correct type.

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

Namespace pollution. A cell is pollution if the header contained a declaration that is not allowed by the POSIX standard under the effective feature macro, or if it had the wrong type. Click the pollution link in the cell to see the rejected declarations.

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

§. The § link on the left of each row links to that row.

namespace

This suite tests for namespace pollution in the standard headers.

The system headers are preprocessed and compared with the API definition files from the include suite, which states what declarations are allowed per each POSIX option. Each header is compiled twice, first with _POSIX_C_SOURCE, and secondly with _XOPEN_SOURCE, and each declaration is verified. The header test will fail if any declaration exists that is not part of the POSIX API, or if the declaration has the wrong type, unless the declaration is inside the header's reserved namespace.

Click the pollution link for any failing headers to see what declarations were rejected.
