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

• errno.h
• fcntl.h
• stdio.h
• stdlib.h
• sys/ioctl.h
• unistd.h
• linux/wmi.h

Detected Declarations

• function show_buffer
• function run_wmi_smbios_cmd
• function find_token
• function token_is_active
• function query_token
• function activate_token
• function query_buffer_size
• function main

Annotated Snippet

if (activate_token(buffer, CAPSULE_EN_TOKEN)) {
			printf("activate failed\n");
			ret = -1;
			goto out;
		}
	}
	ret = EXIT_SUCCESS;
out:
	free(buffer);
	return ret;
}

Annotation

• Immediate include surface: `errno.h`, `fcntl.h`, `stdio.h`, `stdlib.h`, `sys/ioctl.h`, `unistd.h`, `linux/wmi.h`.
• Detected declarations: `function show_buffer`, `function run_wmi_smbios_cmd`, `function find_token`, `function token_is_active`, `function query_token`, `function activate_token`, `function query_buffer_size`, `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.
