GTK 1.2 and Threads

[günther <guenther rapp-informatik de>]

Hallo 
I have to implement lex/yacc syntax interpreter that has to work online
every time a character is typed in  entry widget. The changed event
calls
every time callback function. This callback function should push the 
character to the lex/yacc input. But this syntax checker could not be
interrupted only a CR is detected. This means I need 2 asyncron
prozesses
the first to serve the gtk_main_loop with all gtk stuff and the second
the lex/yacc path .
Has gtk 1.2 a thread function to such task?
Where can I find the documentation for this in the manuals?
Can I find a running example in C for the thread how to install and
work.

Thanks for help
günther
