/* reentrant system call template */

/* Lots of system calls are trivial functions, so we build their source files
4
   from a template.  New syscalls can be added simply by editing the
5
   Makefile!
6
 
7
   The system calls aren't necessarily reentrant.  If we were being used in
8
   an embedded system they could be.  Reentrant syscalls are also used,
9
   however, to provide ANSI C namespace clean access to the host o/s.

   Usage: Compile this file with "func" set to the name of the syscall.  */
