MODULEENTRY32

Describes an entry from a list that enumerates the modules used by a specified process.

typedef struct tagMODULEENTRY32 { 
  DWORD   dwSize; 
  DWORD   th32ModuleID; 
  DWORD   th32ProcessID; 
  DWORD   GlblcntUsage; 
  DWORD   ProccntUsage; 
  BYTE  * modBaseAddr; 
  DWORD   modBaseSize; 
  HMODULE hModule; 
  TCHAR   szModule[MAX_MODULE_NAME32 + 1]; 
  TCHAR   szExePath[MAX_PATH]; 
} MODULEENTRY32; 
typedef MODULEENTRY32 *PMODULEENTRY32; 

Members

dwSize

Specifies the length, in bytes, of the structure. Before calling the Module32First function, set this member to sizeof(MODULEENTRY32). If you do not initialize dwSize, Module32First will fail.

th32ModuleID

Module identifier in the context of the owning process. The contents of this member has meaning only to the tool help functions. It is not a handle, nor is it usable by Win32 API elements.

th32ProcessID

Identifier of the process being examined. The contents of this member can be used by Win32 API elements.

GlblcntUsage

Global usage count on the module.

ProccntUsage

Module usage count in the context of the owning process.

modBaseAddr

Base address of the module in the context of the owning process.

modBaseSize

Size, in bytes, of the module.

hModule

Handle to the module in the context of the owning process.

szModule

String containing the module name.

szExePath

String containing the location (path) of the module.

Note  The modBaseAddr and hModule members are valid only in the context of the process specified by th32ProcessID.

Requirements

  Windows NT/2000: Requires Windows 2000.
  Windows 95/98: Requires Windows 95 or later.
