API-MS-Win-Service-Management-L2-1-0

All functions in the API-MS-Win-Service-Management-L2-1-0 set are documented exports from ADVAPI32:

• ChangeServiceConfigW
• ChangeServiceConfig2W
• NotifyServiceStatusChangeW
• QueryServiceConfigW
• QueryServiceConfig2W
• QueryServiceObjectSecurity
• QueryServiceStatusEx
• SetServiceObjectSecurity

The implementations in ADVAPI32 version 6.1 and higher are just stubs which transfer the handling to wherever the schema redirects the API Set.

New Locations

Non-trivial implementations of all functions in this API Set are exported from SECHOST version 6.1 and higher.

Schema Redirection

The Windows 7 schema redirects this API Set to SECHOST. Thus:

• high-level executables, which do not use the API Set, continue to import these functions from ADVAPI32;
• low-level executables have their imports from the API Set redirected to SECHOST;
• as a particular case of the preceding, the stub implementations in ADVAPI32 import from underlying implementations in SECHOST.
