svn commit: r315525 - head/usr.bin/truss

[John Baldwin]

Author: jhb

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.
