NtOpenCpuPartition

Other → NTSTATUS

NtOpenCpuPartition is a Windows NT kernel system call, in the Other category, returning NTSTATUS. Its syscall number is not the same on every Windows release: across the 6 version-and-architecture pairs recorded here it takes 3 distinct values, from 0x0124 to 0x0126.

The number is an index into the system service table of one particular build, not a stable identifier, so it is not portable between Windows versions. The table below gives the value recorded for each.
