Revision 1.1.2.12 2001/12/03 03:11:05 carl
* update for new posix prototype (caused problem with other OS)
Revision 1.1.2.11 2001/08/22 02:38:12 carl
- sys_exit now written in assembler
Revision 1.1.2.10 2001/08/15 01:01:51 carl
- moved SysCall to syscall.inc
Revision 1.1.2.9 2001/08/13 09:40:43 carl
* bugfix of problems of changing signs with errno!
* changed prototype of sys_readdir() to conform to POSIX
Revision 1.1.2.8 2001/08/13 05:57:53 carl
* corrected written/read value returned for sys_read() and sys_write(). errno now correctly set.
Revision 1.1.2.7 2001/08/12 15:15:21 carl
* bugfix of call to sys_time (would always return weird results)
Revision 1.1.2.6 2001/08/09 01:12:46 carl
* fstat() call now correct
+ ftruncate() support
Revision 1.1.2.5 2001/08/08 01:55:43 carl
* bugfix of sys_opendir()
* bugfix of sys_readdir() should be var parameter not const :(
Revision 1.1.2.4 2001/07/14 04:20:33 carl
+ sys_lseek()
