CURPROC(9)             NetBSD 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.
