Annotated Snippet

if (memcmp(usermap, kernelmap, MAX_OFFSET) != 0) {
					printf("memmove failed at %ld %ld %ld\n",
							src_off, dst_off, len);
					abort();
				}
			}
		}
	}
	return 0;
}

int main(void)
{
	return test_harness(testcase_run, "memmove");
}

Annotation

• Immediate include surface: `malloc.h`, `stdlib.h`, `string.h`, `assert.h`, `utils.h`.
• Detected declarations: `function max`, `function testcase_run`, `function main`.
• 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.
