<![CDATA[[Solved][Moved] Can not use ioctl in Qt 4]]>Hi all. Trying to call ioctl function in Qt, Receive the error message ioctl not declared in this scope. Searched for ioctl in include directory - nothing, as well as iostl.h. Any advises. Thanks

This is a pure C/C++ problem.

try as the man pages ("Linux":http://linux.die.net/man/2/ioctl, "FreeBSD":http://www.freebsd.org/cgi/man.cgi?query=ioctl&sektion=2) suggest:

@
#include <sys/ioctl.h>
