+
+; 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 the types described below, or one of the
+;		compatibility options defined in syscalls.conf
+;
+; types:
+;	INDIR	included, but don't define the syscall args structure,
+;		and allow it to be "really" varargs
+;	NOARGS	included, but don't define the syscall args structure
+;	NODEF	included, but don't define the syscall number
+;	NOLOCK	don't acquire the kernel lock when calling this syscall
+;	OBSOL	obsolete, not included in system
+;	STD	always included
+;	UNIMPL	unimplemented, not included in system
+;
+; 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>

+
+; Reserved/unimplemented system calls in the range 0-150 inclusive
