I don't know why you are using C; a simple shell wrapper should work,
something like:
#! /bin/sh
echo "Status: 200 OK" # strictly should be pending not OK code
# but I don't have the HTTP spec to hand
echo "Content-Type: text/html"
echo
echo "<HTML><HEAD><TITLE>Tony's Page Request Acceptance Page</TITLE>"
echo "</HEAD><BODY><H1>Page Accepted</H1>Your page request has be queued"
echo "for transmission.</BODY></HTML>"
exec /usr/local/bin/sendpage -q -ptony "hello...testing" > /dev/null
# sendpage command not verified
You could use text/plain and return the actual response from sendpage. To
include it in HTML, you will need to bracket it in <PRE></PRE> and translate
& < > and possibly " into entities (e.g. use sed).
You might want to look at the cgiparse utility that comes with the CERN
server.

A valid CGI program must output at least "Location: url" or "Content-Type:
xxx/yyy" followed by a blank line. "Status: 204 No output" ought also
to be OK, again followed by a blank line.

The output from sendpage is on standard output, or possibly standard error.
It ALSO returns an int return code.
Note that the above is telling you the requirements for a CGI script - it
is possible that sendpage has other requirements on its environment.
