示例

#include <windows.h>
#include <iostream.h>
#include "Shlwapi.h"

void main( void )
{
// String path name 1.
char buffer_1[ ] = "http://www.microsoft.com/software/index.html";
char *lpStr1;
lpStr1 = buffer_1;

// String path name 2.
char buffer_2[ ] = "http://www.microsoft.com";
char *lpStr2;
lpStr2 = buffer_2;

// String path name 3.
char buffer_3[ ] = "microsoft.com";
char *lpStr3;
lpStr3 = buffer_3;

// Variable to get the return 
// from "PathIsURL".
int retval;

// Test path name 1.
retval = PathIsURL(lpStr1);
cout << "The contents of String 1: " << lpStr1
     << "\nThe return value from the function is " << retval << " = TRUE" << endl;

// Test path name 2.
retval = PathIsURL(lpStr2);
cout << "The contents of String 2: " << lpStr2
     << "\nThe return value from the function is " << retval << " = TRUE" << endl;

// Test path name 3.
retval = PathIsURL(lpStr3);
cout << "The contents of String 3: " << lpStr3
     << "\nThe return value from the function is " << retval << " = FALSE"<< endl;
}

OUTPUT:
=============
The contents of String 1: http://www.microsoft.com/software/index.html
The return value from the function is 1 = TRUE
The contents of String 2: http://www.microsoft.com
The return value from the function is 1 = TRUE
The contents of String 3: microsoft.com
The return value from the function is 0 = FALSE
