NAME
curproc,
curcpu,
curlwp
—
current process, processor, and LWP
SYNOPSIS
#include <sys/proc.h>
struct cpu_info *
curcpu(
void);
struct proc *
curproc(
void);
struct lwp *
curlwp(
void);
DESCRIPTION
The following macros can be used to retrieve the current processor, process, and
light-weight process (LWP), respectively:
- The machine-dependent curcpu() macro
returns a pointer to a cpu_info structure containing
information of the CPU that this thread is running on.
- The machine-independent curproc() macro
refers to a pointer to the process currently running on this CPU.
- The curlwp() macro expands to a pointer
to lwp structure, containing information about the
current LWP. This macro is machine-independent, but machine-dependent
<machine/cpu.h> may redefine
it.
