Dear all,
I know the use of fprintf and typecasting. But, in the following function call what is the use? why that is type casted to void?

(void) fprintf(stderr, "Enter key: ");

Some shops require that code pass lint with no warnings. fprintf returns n int. If you do not need/want to check the return value, cast it to void. Then lint will not complain about it. And code reviewers will know that you are aware of the consequences. HPUX man page examples often have this.
