Support Tooling And Documentation: implementation source

source implementation candidate

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

• No C-style include directives detected by the generator.

Detected Declarations

• struct srccode_state
• function srccode_state_init

Annotated Snippet

struct srccode_state {
	char	 *srcfile;
	unsigned line;
};

static inline void srccode_state_init(struct srccode_state *state)
{
	state->srcfile = NULL;
	state->line    = 0;
}

void srccode_state_free(struct srccode_state *state);

/* Result is not 0 terminated */
char *find_sourceline(char *fn, unsigned line, int *lenp);

#endif

Annotation

• Detected declarations: `struct srccode_state`, `function srccode_state_init`.
• 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.
