NtSetContextChannel
Set → NTSTATUS
NtSetContextChannel is a Windows NT kernel system call, in the Set category, returning NTSTATUS. Its syscall number is not the same on every Windows release: across the 13 version-and-architecture pairs recorded here it takes 4 distinct values, from 0x00D0 to 0x00F6.
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.
