+
+; 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.

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

+; Additional system calls implemented in vendor and other
