amiga-clib2/library/include/unistd.h
Olaf Barthel 8555296691 c.lib 1.177 (29.9.2004) 
- Moved the locale initialization/cleanup code into constructors
  and destructors.

- The socket cleanup function is now a destructor.

- The math cleanup function is now a destructor.

- The wildcard cleanup function is now a destructor.

- The stdio cleanup function is now a destructor.

- The stack extension cleanup function is now a destructor.

- The code that cleans up after the program's current directory
  was changed is now a destructor function.

- Moved the initialization/cleanup code for unlink() into constructors
  and destructors.

- Moved the initialization/cleanup code for usergroup.library into
  constructors and destructors.

- Added usleep(), and created wrapper code that both sleep() and
  usleep() can use.

- Added strtoll() and strtoull(), with further changes to <limits.h>
  and <stdlib.h>.
