<H2><A NAME="xpacode">XPACode: Where to Find Example/Test Code</A></H2>
<!-- =section xpacode SYNOPSIS -->
<H2>Summary</H2>
<P>
The XPA source code directory contains two test programs,
<EM>stest.c</EM>, and <EM>ctest.c</EM> that can serve as
examples for writing XPA servers and clients, respectively.
They also can be used to test various features of XPA.
<!-- =section xpacode DESCRIPTION -->
<H2>Description</H2>
<P>
To build the XPA test programs, execute:
<PRE>
make All
</PRE>
in the XPA source directory to generate the <EM>stest</EM> and
<EM>ctest</EM> programs. (NB: this should work on all platforms,
although we have had problems with unresolved externals on one
Sun/Solaris machine, for reasons still unknown.)
<P>
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.
You then can use xpaset and xpaget to interact with these access points:
<PRE>
cat xpa.c | 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
</PRE>
etc. You also can use ctest to do the same thing, or to iterate:
<PRE>
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
</PRE>
More options are available: see the stest.c and ctest.c code itself, which
were used extensively to debug XPA.
<P>
The file test.tcl in the XPA source directory gives examples for using the
<A HREF="./tcl.html">XPATcl</A>Interface.
