p Currently .Nm supports only TCP/IP related system calls. The set of supported subsystems may change later along with the usage of the library. .Sh EXAMPLES Use an alternate TCP/IP stack for firefox: d -literal -offset indent $ setenv RUMP_SERVER unix:///tmp/tcpip $ setenv LD_PRELOAD /usr/lib/librumphijack.so $ firefox .Ed .Sh SEE ALSO .Xr ld.so 1 , .Xr rump_server 1 , .Xr rump 3 , .Xr rump_sp 7
