Revision 1.1 2002-08-19 12:29:11 marco
* First working POSIX *BSD system unit.
Revision 1.2 2002/08/04 04:29:34 marco
* More POSIX updates. Small changes to lseek and ftruncate in osposix.inc
Initial versions of the type includefiles
Revision 1.1 2002/08/03 19:34:19 marco
* Initial *BSD versions. Seems that OpenBSD doesn't need much change,
NetBSD may need some fixes to stat record and ftruncate and lseek.
It is all close together, and it should be doable to have just one copy
of these for *BSD.
Revision 1.1.2.5 2001/12/09 03:31:50 carl
+ wifsignaled() added
Revision 1.1.2.4 2001/12/03 03:13:30 carl
* fix ftruncate prototype
* fix rename prototype
* change readdir / closedir prototype
Revision 1.1.2.3 2001/11/30 03:50:43 carl
+ int -> cint
+ missing prototypes added
Revision 1.1.2.2 2001/11/28 03:08:29 carl
* int -> cint
+ several other stuff renamed
Revision 1.1.2.1 2001/08/15 00:15:04 carl

Implements roughly POSIX 1003.1 conforming interface for *BSD
Declarations to import basic syscalls declarations into other base
units.
The conditional uselibc can be used to switch from libc to syscall
usage for basic primitives, but it is best to use unit POSIX if
possible. Note that the system unit must also be compiled using uselibc.
