RT。
编译完后提示
[Linker error] undefined reference to `GetProcessMemoryInfo@12'

是什么意思？？？

用GetProcessMemoryInfo这个api，下面这个函数当参考

void PrintMemoryInfo( DWORD processID )
{
HANDLE hProcess;
PROCESS_MEMORY_COUNTERS pmc;

// Print the process identifier.

printf( "\nProcess ID: %u\n", processID );

// Print information about the memory usage of the process.

hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
PROCESS_VM_READ,
FALSE, processID );
if (NULL == hProcess)
return;

if ( GetProcessMemoryInfo( hProcess, &pmc, sizeof(pmc)) )
{
printf( "\tPageFaultCount: %d\n", pmc.PageFaultCount );
printf( "\tPageFaultCount: 0x%08X\n", pmc.PageFaultCount );
printf( "\tPeakWorkingSetSize: 0x%08X\n",
pmc.PeakWorkingSetSize );
printf( "\tWorkingSetSize: 0x%08X\n", pmc.WorkingSetSize );
printf( "\tQuotaPeakPagedPoolUsage: 0x%08X\n&
