;	@(#)syscalls.master	8.2 (Berkeley) 1/13/94

; OpenBSD system call name/number "master" file.
; (See syscalls.conf to see what it is processed into.)
;
; Fields: number type [type-dependent ...]
;	number	system call number, must be in order
;	type	one of STD, OBSOL, UNIMPL, NODEF, NOARGS, or one of
;		the compatibility options defined in syscalls.conf.
;
; types:
;	STD	always included
;	OBSOL	obsolete, not included in system
;	UNIMPL	unimplemented, not included in system
;	NODEF	included, but don't define the syscall number
;	NOARGS	included, but don't define the syscall args structure
;	INDIR	included, but don't define the syscall args structure,
;		and allow it to be "really" varargs.
;
; The compat options are defined in the syscalls.conf file, and the
; compat option name is prefixed to the syscall name.  Other than
; that, they're like NODEF (for 'compat' options), or STD (for
; 'libcompat' options).
;
; The type-dependent arguments are as follows:
; For STD, NODEF, NOARGS, and compat syscalls:
;	{ pseudo-proto } [alias]
; For other syscalls:
;	[comment]
;
; #ifdef's, etc. may be included, and are copied to the output files.
; #include's are copied to the syscall switch definition file only.

#include <sys/param.h>
#include <sys/systm.h>
#include <sys/signal.h>
#include <sys/mount.h>
#include <sys/syscallargs.h>
#include <sys/poll.h>

; Reserved/unimplemented system calls in the range 0-150 inclusive
; are reserved for use in future Berkeley releases.
; Additional system calls implemented in vendor and other
; redistributions should be placed in the reserved range at the end
; of the current calls.
