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

• stddef.h
• stdbool.h

Detected Declarations

• struct dirent

Annotated Snippet

#ifndef _PERF_PATH_H
#define _PERF_PATH_H

#include <stddef.h>
#include <stdbool.h>

struct dirent;

int path__join(char *bf, size_t size, const char *path1, const char *path2);
int path__join3(char *bf, size_t size, const char *path1, const char *path2, const char *path3);

bool is_regular_file(const char *file);
bool is_directory(const char *base_path, const struct dirent *dent);
bool is_directory_at(int dir_fd, const char *path);

#endif /* _PERF_PATH_H */

Annotation

• Immediate include surface: `stddef.h`, `stdbool.h`.
• Detected declarations: `struct dirent`.
• 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.
