Syntax

BOOL WINAPI Module32First( HANDLE hSnapshot, LPMODULEENTRY32 lpme);

Parameters

hSnapshot

Handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function.

lpme

Pointer to a MODULEENTRY32 structure.

Return Value

TRUE indicates that the first entry of the module list has been copied to the buffer. FALSE indicates failure. The ERROR_NO_MORE_FILES error value, returned by GetLastError, indicates that 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. Module32First changes dwSize to the number of bytes written to the structure. This will never be greater than the initial value of dwSize, but it may be smaller. If the value is smaller, do not rely on the values of any members whose offsets are greater than this value.

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