API-MS-Win-Core-Interlocked-L1-1-0

All functions in the API-MS-Win-Core-Interlocked-L1-1-0 set are exports from KERNEL32, some from x86 builds only:

• InitializeSListHead
• InterlockedCompareExchange (x86 only)
• InterlockedCompareExchange64 (x86 only)
• InterlockedDecrement (x86 only)
• InterlockedExchange (x86 only)
• InterlockedExchangeAdd (x86 only)
• InterlockedFlushSList
• InterlockedIncrement (x86 only)
• InterlockedPopEntrySList
• InterlockedPushEntrySList
• InterlockedPushListSList
• QueryDepthSList

All these functions are either forwarded to a corresponding NTDLL function or have an intrinsic implementation in KERNEL32.

New Locations

Both the forwarding and the implementations are duplicated in KERNELBASE version 6.1 and higher.

Schema Redirection

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

• high-level executables, which do not use the API Set, continue to import these functions from KERNEL32;
• low-level executables have their imports from the API Set redirected to KERNELBASE.
