about out_io systemcall
 

hai friends,
i need some information regarding "out_io()" system call.i tink it is rtlinux system call,is it right or not?. please tell me what is the functionality of this system call.
thank u

Please give more details. This definitely is not a linux system call. Some preliminary search results show a few uses of this in perl, and a few non-general uses in C.

Exactly what are you talking about here?

P.S., all the linux system calls for your platform should be located in <asm/unistd.h> header.
