Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/signal.h
• system.h

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

#ifndef SIGNAL_H
#define SIGNAL_H

#include <linux/signal.h>

#include "system.h"

typedef __sighandler_t sighandler_t;

int sigemptyset(sigset_t *s);
int sigaddset(sigset_t *s, int n);
int sigaction(int n, struct sigaction *sa, const struct sigaction *old);
int sigprocmask(int how, const sigset_t *mask, sigset_t *old);

#endif /* ! SIGNAL_H */

Annotation

• Immediate include surface: `linux/signal.h`, `system.h`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
