RtGetProcessAffinityMask
RtGetProcessAffinityMask retrieves the process affinity mask for the specified process and the system affinity mask for Process.
Syntax
BOOL RtGetProcessAffinityMask(
HANDLE hProcess,
PUINT64 pProcessAffinityMask,
PUINT64 pSystemAffinityMask
);
Parameters
hProcess
A handle to the process whose affinity mask is desired.
pProcessAffinityMask
A pointer to a variable that receives the affinity mask for the specified process.
pSystemAffinityMask
A pointer to a variable that receives the system affinity mask for Process.
Return Value
If the function succeeds, it returns a non-zero value. The function sets the variables pointed to by lpProcessAffinityMask and lpSystemAffinityMask to the appropriate affinity masks.
If the function fails, it returns 0 (zero). The values of the variables pointed to by lpProcessAffinityMask and lpSystemAffinityMask are undefined.
To get extended error information, call GetLastError.
Remarks
A process affinity mask is a bit vector in which each bit represents the processors that a process is allowed to run on. A system affinity mask is a bit vector in which each bit represents the processors that are dedicated to Process.
