/* reentrant system call template */

/* Lots of system calls are trivial functions, so we build their source files

   from a template.  New syscalls can be added simply by editing the

   Makefile!

   The system calls aren't necessarily reentrant.  If we were being used in

   an embedded system they could be.  Reentrant syscalls are also used,

   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.  */
