Module32First Function

Retrieves information about the first module associated with a process.

Syntax

C++
BOOL WINAPI Module32First(
  __in     HANDLE hSnapshot,
  __inout  LPMODULEENTRY32 lpme
);

Parameters

hSnapshot [in]

A handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function.

lpme [in, out]

A pointer to a MODULEENTRY32 structure.

Return Value

Returns TRUE if the first entry of the module list has been copied to the buffer or FALSE otherwise. The ERROR_NO_MORE_FILES error value is returned by the GetLastError function if no modules exist or the snapshot does not contain module information.

Remarks

The calling application must set the dwSize member of MODULEENTRY32 to the size, in bytes, of the structure.

To retrieve information about other modules associated with the specified process, use the Module32Next function.
