CURPROC(9)		 BSD Kernel Developer's Manual		    CURPROC(9)

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:

	   1.	The machine-dependent curcpu() macro returns a pointer to a
		cpu_info structure containing information of the CPU that this
		thread is running on.

	   2.	The machine-independent curproc() macro refers to a pointer to
		the process currently running on this CPU.

	   3.	The curlwp() macro expands to a pointer to lwp structure, con‐
		taining information about the current LWP.  This macro is
		machine-independent, but machine-dependent <machine/cpu.h> may
		redefine it.
