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.
