Re: Controlling gdb outside the terminal

[Brother Josef <thykeeper@nerdshack.com>]

excellent, thank you. and yes actually I do need to look into MI  
mode, I'm new to GDB and just now considering it as the future in how  
I might be debugging. Could I run GDB without that error and continue  
to write and read from the program from within my Mac app?

Could anyone point me to any source code on pseudo-terminals or  
documents? I have been looking around today and I still can't get a  
clear picture of how such code would look providing I could even  
write it. ;) thanks again
