Members

dwFlags

Reserved.

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

Null-terminated string that contains the module name.

szExePath

Null-terminated string that contains the location (path) of the module.

Remarks

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