How to Instantiate a Templated Function

MORE INFORMATION

• In the source file where the function is defined, explicitly reference the function by taking the address of the function. -or-
  
  
• In the source file where the function is defined, add a dummy function that makes a call to the templated function. The dummy function itself does not need to be called.

Sample Code

/* Compile options needed: none
*/ 

/********** Source File One **********/ 
void func1(void);
template < class T> T SwapTemplate(T Source) {
   return Source;
}
void Dummy(void) {                            // Option One
   char a = 'a', b;
   b = SwapTemplate(a);
}

void main() {
   int (*pfunc)(int) = SwapTemplate;     // Option Two
   func1();
}
				

/********** Source File Two **********/ 

template < class T> T SwapTemplate(T Source); // Prototype

void func1(void) {
   int  a = 5, b;
   char c = 'c', d;
   b = SwapTemplate( a );
   d = SwapTemplate( c );
}
