How to use GetProcessImageFileName?

Question

I'm trying to use GetProcessImageFileName but I'm getting the following error:

Undeclared identifier: 'GetProcessImageFileName'

I've tried adding PsAPI and TlHelp32 to the uses clause but it has not solved the problem.

I'm not sure if this function is supplied by the RTL anywhere, but you can always just import it :

function GetProcessImageFileName(hProcess: THandle; 
                                 lpImageFileName: LPTSTR;
                                 nSize: DWORD): DWORD; stdcall;
                                 external 'PSAPI.dll' 
                                 name 'GetProcessImageFileNameA';

The ANSI version (for Delphi 2007) is imported above. Alternatively, if supporting higher versions of delphi (with unicode strings) you would conditionally import GetProcessImageFileNameW.
