The XPA source code directory contains two test programs, stest.c , and ctest.c that can serve as examples for writing XPA servers and clients, respectively. ... The stest program can be executed with no arguments to start an XPA server that contains the access points: xpa, xpa1, c_xpa (containing sub-commands cmd1 and cmd2), and i_xpa. ... xpaset xpa # send to xpa cat xpa.c | xpaset "xpa*" # send to xpa and xpa1 xpaget xpa # receive from xpa xpaget xpa* # receive from xpa and xpa1 etc. ...

... will give a .\" real vertical bar. ... xpaset xpa # send to xpa \& cat xpa.c | ... You also can use ctest to do the same thing, or to iterate: .PP .Vb 4 \& ctest -s -l 100 xpa # send to xpa 100 times \& ctest -s -l 100 "xpa*" # send to xpa and xpa1 100 times \& ctest -g -l 100 xpa # receive from xpa 100 times \& ctest -g -l 100 "xpa*" # receive from xpa and xpa1 100 times .Ve .PP More options are available: see the stest.c and ctest.c code itself, which were used extensively to debug \s-1XPA\s0. ...
