Question

I wrote the following code snippet in VS2010:

#pragma once
#include "stdafx.h"
#ifndef SECURITY_WIN32
#define SECURITY_WIN32
#endif
#include "windows.h"
#include "sspi.h"

int main( void )
{
    ULONG cPackages = 0;
    PSecPkgInfo pInfo = NULL;
    SECURITY_STATUS stat = EnumerateSecurityPackages(&cPackages, &pInfo);
    if (stat == SEC_E_OK) 
    { 
        for (ULONG i = 0; i < cPackages; i++) 
        { 
            wprintf(L"%s\t%s\n",pInfo[i].Name, pInfo[i].Comment); 
        } 
        FreeContextBuffer(pInfo); 
    } 
    return 0; 

}

but, at the compile time I got the following errors:

error LNK2019: unresolved external symbol
_imp_EnumerateSecurityPackagesW@8 referenced in function _main

and

error LNK2019: unresolved external symbol _FreeContextBuffer@4
referenced in function _main

can anyone please help me?

You need to link against Secur32.lib.

Go to Project Properties -> Linker -> Input and add Secur32.lib in the list.
