That's surely legal, but I usually find

if ( !(fp = fopen(whatever, "r")){ error_message();}

a little more readable. Anyway, I always prefer to disentangle
assignments and conditional expressions, just and only for the sake of
improving readability:

fp = fopen(whatever, "r");
if (!fp){error_message();}

Debugging C code is already a pain in the ass, so there is no reason
to make it even more painful with syntax back somersaults....
