Re: lynx-dev Q: control lynx from C

[Klaus Peter Wegge]

there is a very simple way to control lynx 
from a C Programm. Perhaps this is, what you are looking for!
Compile the very small "lynxin" programm attached to this mail.
I tested it in LINUX.
Then type:
lynxin | lynx

lynxin will read the keystrokes from the keybord and flush them to
stdout imediately.
OK, this program is rather silly.
But you can use it as a skeleton for example for connecting a voice
recognition machine as a frontend to lynx without modifying
lynx.
