Your primary question has already been answered by Werner, but I also want
to encourage you to use command-line options rather than hard coding
devices, filenames, and geometries. Thus, I would advise replacing the
plsdev and plsfnam commands above with
(void) plparseopts(&argc, argv, PL_PARSE_FULL);
Then run your application like this:
./myplplot_application -dev png -o tmp.png -geometry 800x600
If you want to see the equivalent PostScript results, then use
./myplplot_application -dev psc -o tmp.ps
To find all command-line options available to you use
./myplplot_application -h
