tkchia 15955282f6 plat/msdos386: fix some issues in libsys code ... - ensure es = ds = ss upon exit of each C runtime function - clear upper 16 bits of ebx before setting them to 0x0021, when invoking interrupt_ptr to simulate a RM int 0x21 - make _sys_exists use the transfer buffer (which it needs) - make _sys_rawread properly handle an end-of-file read (zero bytes read) - make argument to _sys_seterrno short --- after a failed int 0x21 call, only the lower 16 bits of eax hold the MS-DOs error code - _sys_rawlseek accepts only 3 longword arguments, not 4 (the offset is only 1 longword) - other minor fixes		2022-08-24 15:17:04 +00:00
