Hi I am quite new to the Mac world...I am trying to write(using xcode on tiger) a simple character driver(openbsd.org example) and am facing few problems...

During compile, struct uio is not recognized and I get a dereferencing pointer to incomplete type error...can somebody help...maybe I am not including the correct libraries...

<....> MacOSX does not allow access to core kernel structures like uio on the theory that Apple may want to change them some day, and does not want to break binary drivers when the structure changes. This is generally called the "KPI".

amt = MIN(uio->uio_resid, (echomsg->len - uio->uio_offset > 0) ?

For example, in the above code you want to use uio_resid(uio) and uio_offset(uio). Drew _______________________________________________ Do not post admin requests to the list. They will be ignored.
