If you know the name of the function, if it is foo, you just say &foo

Your compiler might or might not let you convert a function pointer to a
char pointer.  If it lets you, the result might or might not be usable.
And if you can convert back, it might again be unusable.  Safer is:
void (*fcn)();
void foo() {
	fcn = &foo;
}
