Writing to files from outside the function they were opened in

Is there any way of doing this?

I need to open up an output text file in the main function (where argv is) and then write to it from within a function called by main, yyparse(void). This function is generated by bison and I don't know any way of adding parameters to it.

Any help would be appreciated,

Felix

Well the 'right' way of doing it would involve adding parameters to your yyparse function. You need to pass the file descriptor so the function knows about it.
