Setting up external functions to be called from Mathematica

Hi,
I'm trying to figure out how to call an external function from
Mathematica. Examples I've found so far doesn't give enough
informations for a newbie like myself.
The following is content of an example MathLink template file, f.tm:
:Begin:
:Function: f
:Pattern: f[x_Integer, y_Integer]
:Arguments: {x, y}
:ArgumentTypes: {Integer, Integer}
:ReturnType: Integer
:End:
1. How do I create a MathLink template? Can I just use text editor
and save it with .tm extension? Where should the file be saved?
Following is the content of an example c code, I named it f.c:
#include "mathlink.h"
int main(int argc, char *argv[]) {
return MLMain(argc, argv);
}
int f(int x, int y) {
return x+y;
}
2. Although I copied "mathlink.h" file into INCLUDE folder for C
compiler (I'm temporarily using Dev-C++), the compiler doesn't
recognize MLMain(argc, argv); Can anyone tell why? Does this have to
do w/ the kind of compiler I'm using? Does this c file need to be in
the same folder as the above .tm file?
3. After I get these files saved in the right folders, how do I use
them?
Any help would be greatly appreciated!!!
