QUESTION

Help. I receive the following warning when I compile my C code.

*** WARNING 140 IN LINE 14 OF .TEST.C: 'func' undefined; assuming 'extern int func()'

How can I fix this?

ANSWER

This warning indicates that the func function is undefined. The compiler is going to assume that the function is declared as int func ().

To get rid of this warning, you must create a function prototype for the undefined function. For example:

void func (int a, int b);

void main (void)
{
func (1, 2);
}
