GetProcessImageFileName not linking

Question

Im trying to use GetProcessImageFileName. I have included Psapi.h but when i try ti compile i get

error LNK2019: unresolved external symbol _GetProcessImageFileNameA@12 referenced in function "bool __cdecl FindProcesses(char const *,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > *)" (?FindProcesses@@YA_NPBDPAV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z)99>G:\Test\main\Tests.exe : fatal error LNK1120: 1 unresolved externals

The function comes up in Itellisense so can anyone tell me why it wont compile?

Answer 1

This is a linker failure (it does compile) and is unrelated to the inclusion of Psapi.h. You probably need to link with Psapi.lib.

For specific instructions on what library to link with see the Library section from the GetProcessImageFileName() reference page:

Kernel32.lib on Windows 7 and Windows Server 2008 R2; 
Psapi.lib (if PSAPI_VERSION=1) on Windows 7 and Windows Server 2008 R2; 
Psapi.lib on Windows Server 2008, Windows Vista, Windows Server 2003,
and Windows XP
