    Ok here is just a quickie. Demonstrating the "function pointer." This is 
sloppy because I did get these two warnings after compilation. And I know if 
something was passed to the print wrapper function and the printf specifier 
needed to be something other than %s there would be a problem. But this is 
as I say just a quickie.

#include <stdio.h>

int print(char *);
int (*pf) (char *);

int main()
{
    pf = print("hello there");
    return pf;
}

int print(char *input)
{
    printf("%s\n", input);
    return 0;
}

    And the warnings:

p.c: In function 'main':
p.c:8:8: warning: assignment makes pointer from integer without a cast 
[enabled by default]
     pf = print("hello there");
        ^
p.c:9:5: warning: return makes integer from pointer without a cast [enabled 
by default]
     return pf;
     ^

I did not use -Wall either. as the compiler says "enabled by default. It 
compiles and runs.
