C example – SIOCSPARTNERINFO and SIOCGPARTNERINFO ioctl calls

The following sample C code builds and issues the SIOCSPARTNERINFO and SIOCGPARTNERINFO ioctl calls. The SIOCGPARTNERINFO ioctl retrieves the connection routing information and the security credentials of a partner. The optional SIOCSPARTNERINFO ioctl enables an application to avoid suspending while retrieving partner security credentials with the SIOCGPARTNERINFO ioctl.
