Date: 16 May 95 18:50:54 GMT Organization: Delphi Internet Services Corporation Lines: 14 Message-ID: <sysec.800650254@BIX.com> NNTP-Posting-Host: bix.com Needing to send data to ports directly I saw that there is no outb() and outw() in the FreeBSD 1.1.5 libs, so I took the assembler source from the kernel distribution and plug it into my src. It compile fine but it cores. I'm sure that is a problem in the integration of the asm code with my C program since it cores even if the outb() has a 'ret'. What are the precautions I must take when integratin asm code ? Any compiler switch ? Any as switch ? What about ld ? Help me out please. (sources would help.) THanks.
