/* 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. */
