cg_current(2)
cg_current --
obtain identifier for the current CPU-Group
Synopsis
#include <sys/cguser.h>
cgid_t cg_current(
idtype_t idtype,
id_t id);
Description
cg_current returns the identity of the CPU-Group to which
the specified process or LWP belongs.
The combination of idtype and id specifies the process
or LWP of interest.
When idtype is P_PID, id is interpreted as
a process id; the special value P_MYID may be used as shorthand
for the calling process. When idtype is P_LWPID, id is
interpreted as the LWP id of an LWP within the calling
process; the special value P_MYID may be used as shorthand for
the calling LWP.
Return values
On success, cg_current returns a CPU-Group identifier.
On failure, cg_current returns (cgid_t)-1 and sets
errno to indicate the error:
[EINVAL]-
idtype has an invalid value.
[EINVAL]-
An invalid process or LWP id was supplied.
[ESRCH]-
No process can be found corresponding to that specified by id.
[ENOSYS]-
The cg_current call is not supported by the system.
