From d426b045332718ae6d42237303d657fd97c51455 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Mon, 23 Jul 2012 16:54:53 -0400 Subject: add ioperm/iopl syscalls based on patches by orc and Isaac Dunham, with some fixes. sys/io.h exists and contains prototypes for these functions regardless of whether the target arch has them; this is a bit unorthodox but I don't think it will break anything. the function definitions do not exist unless the appropriate SYS_* syscall number macro is defined, which should make sure configure scripts looking for these functions don't find them on other systems. presently, sys/io.h does not have the inb/outb/etc. port io macros/functions. I'd be surprised if ioperm/iopl are useful without them, so they probably need to be added at some point in appropriate bits/io.h files... --- include/sys/io.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) create mode 100644 include/sys/io.h (limited to 'include') diff --git a/include/sys/io.h b/include/sys/io.h new file mode 100644 index 00000000..a6ba4674 --- /dev/null +++ b/include/sys/io.h @@ -0,0 +1,13 @@ +#ifndef _SYS_IO_H +#define _SYS_IO_H +#ifdef __cplusplus +extern "C" { +#endif + +int ioperm(unsigned long, unsigned long, int); +int iopl(int); + +#ifdef __cplusplus +} +#endif +#endif -- cgit v1.2.1
