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

NAME
     SYSCALL_MODULE -- syscall kernel module declaration macro

SYNOPSIS
     #include <sys/param.h>
     #include <sys/kernel.h>
     #include <sys/proc.h>
     #include <sys/module.h>
     #include <sys/sysent.h>

     SYSCALL_MODULE(name, int *offset, struct sysent *new_sysent,
	 modeventhand_t	evh, void *arg);

DESCRIPTION
     The SYSCALL_MODULE() macro	declares a new syscall.	 SYSCALL_MODULE() ex-
     pands into	a kernel module	declaration named as name.

     The rest of the arguments expected	by this	macro are:

     offset	 A pointer to an int which saves the offset in struct sysent
		 where the syscall is allocated.

     new_sysent	 is a pointer to a structure that specifies the	function im-
		 plementing the	syscall	and the	number of arguments this func-
		 tion needs (see <sys/sysent.h>).

     evh	 A pointer to the kernel module	event handler function with
		 the argument arg.  Please refer to module(9) for more infor-
		 mation.

     arg	 The argument passed to	the callback functions of the evh
		 event handler when it is called.

EXAMPLES
     A minimal example for a syscall module can	be found in
     /usr/share/examples/kld/syscall/module/syscall.c.
