is it possible to pass a pointer that points to a function with arguments to a function that expects a pointer to a function that has arguments?
(in c)
thanks

Yes, but you must be more specific.

What do you want me to specify

Name: Anonymous 2007-05-15 0:57 ID:tr3ePyu+

void *blah(void *(*sub)(void)) {

  return (void *)0;

}



main() {

  void *(*something)(void *(*sub)(void)) = blah;

  something((void *)0);

}

int blah(int i) { return i + 1; }

void zuh(int (*param)(int)) { param(2); }

int main() { zuh(blah); }

Why would you pass a null function pointer to a function that is expecting to get a pointer to a function it can call?

Because it's stupid as hell. If not, I'll just vote for Barak, the son of Abinoam from Kedesh in Naphtali. His military experience leading the campaign to liberate Israel from the Canaanites will be crucial in the years ahead.

Hell if I know. I just wanted to see if I could get something that takes a function pointer that itself takes a function pointer to compile. And it does.

That, and I was too lazy to come up with another dummy function.
