return the processors within a CPU-Group
cg_processors obtains a list of the processors within a
and stores the result in the array of processor IDs
processorid_array. This array has nprocessorids entries and must be large enough to contain
the entire list.
The cgid parameter specifies the CPU-Group for which
the contained processor identifiers are to be returned.
The special value CG_CURRENT may be used as shorthand for the caller's
The selector parameter takes the value P_ONLINE.
If the CPU-Group is not online, cg_processors fails with EAGAIN.
On success, cg_processors returns the
number of selected processors within the
CPU-Group. On failure, cg_processors returns a value of
-1 and sets errno to indicate the error:
The CPU-Group was not online
selector contains an invalid value
cgid contains an invalid value
The value of nprocessorids is less than the number of
specified processors in the CPU-Group.
A referenced part of the array pointed to by processorid_array is outside of
the allocated address space of the process.
The cg_processors call is not supported by the system.
