; from: @(#)syscalls.master 8.2 (Berkeley) 1/13/94
;
; System call name/number master file.
; Processed to created init_sysent.c, syscalls.c and syscall.h.
; Columns: number type nargs namespc name alt{name,tag,rtyp}/comments
; number system call number, must be in order
; type one of STD, OBSOL, UNIMPL, COMPAT
; namespc one of POSIX, BSD, NOHIDE
; name psuedo-prototype of syscall routine
; If one of the following alts is different, then all appear:
; altname name of system call if different
; alttag name of args struct tag if different from [o]`name'"_args"
; altrtyp return type if not int (bogus - syscalls always return int)
; for UNIMPL/OBSOL, name continues with comments
; types:
; STD always included
; COMPAT included on COMPAT #ifdef
; LIBCOMPAT included on COMPAT #ifdef, and placed in syscall.h
; OBSOL obsolete, not included in system, only specifies name
; UNIMPL not implemented, placeholder only
; #ifdef's, etc. may be included, and are copied to the output files.
#include <sys/param.h>
#include <sys/sysent.h>
#include <sys/sysproto.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.
