Enumerating All Modules For a Process

To determine which processes have loaded a particular DLL, you must enumerate the modules for each process. The following sample code uses the EnumProcessModules function to enumerate the modules of current processes in the system.



The main function obtains a list of processes by using the EnumProcesses function. For each process, the main function calls the PrintModules function, passing it the process identifier. PrintModules in turn calls the OpenProcess function to obtain the process handle. If OpenProcess fails, the output shows only the process identifier. For example, OpenProcess fails for the Idle and CSRSS processes because their access restrictions prevent user-level code from opening them. Next, PrintModules calls the EnumProcessModules function to obtain the module handles function. Finally, PrintModules calls the GetModuleFileNameEx function, once for each module, to obtain the module names.
