New Revision: 315525
URL: https://svnweb.freebsd.org/changeset/base/315525
Log:
Improve decoding of last arguments to ioctl() and sendto().
Decode the last argument to ioctl() as a pointer rather than an int.
Eventually this could use 'int' for the _IOWINT() case and pointers for
all others.
The last argument to sendto() is a socklen_t value, not a pointer.
