Determines whether a path string refers to the root of a volume.

Syntax


BOOL PathIsRoot(
  _In_  LPCTSTR pPath
);

Parameters

pPath [in]

Type: LPCTSTR

A pointer to a null-terminated string of maximum length MAX_PATH that contains the path to be validated.

Return value

Type: BOOL

Returns TRUE if the specified path is a root, or FALSE otherwise.

Remarks

Examples


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

void main( void )
{
// String path name 1.
char buffer_1[ ] = "C:\\";
char *lpStr1;
lpStr1 = buffer_1;

// String path name 2.
char buffer_2[ ] = "path\\file";
char *lpStr2;
lpStr2 = buffer_2;

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

// Test case with path not absolute.
retval = PathIsRoot(lpStr1);
cout << "The return from function is       :" << retval << endl;
cout << "The path does contain a root part :" << lpStr1 << endl;

// Test case with path absolute.
retval = PathIsRoot(lpStr2);
cout << "The return from function is       :" << retval << endl;
cout << "The path does not contain part    :" << lpStr2 << endl;
}

============
The return from function is       :1
