Geomview For Windows?
[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]
Greetings!! My Iris is back on line, and I am learning the Forms package and have an immediate question. In reading the documentation for Forms, I realized that my program will have to do something similar to what your graffiti program does, namely it will have to wait for two different types of events: Forms events, and standard input piped from geomview. So I looked up your source code for graffiti, and I can see that you had to do some rather tricky things in the subroutine gui_mail_loop() in the file gui.c. I have a general understanding of what is happening in this loop: first it checks to see if anything is pending in stdin, if so that is handled via the Lisp library as pick information from geomview; then it calls fl_check_forms() to handle any possible events pending in the Forms queue; then the loop is continued. However, the specifics elude me. The man page for the select() subroutine is gobbledygook to me. That would be OK because I could just copy the code, but what is worse, I can find no information whatsoever for the call to async_fnextc(). In particular, I do not know where to obtain a library routine, or source code, or macro code for async_fnextc(). Any suggestions?? Many thanks for everyone's continued help and support. Sincerely, Lee
