The code I have works, but, is there a better way to do this for =
"GetLogicalDriveStrings"?
--DWORD GetLogicalDriveStrings(
-- DWORD nBufferLength, // size of buffer=20
-- LPTSTR lpBuffer // address of buffer for drive strings=20
-- );=20
. . . . .

if kernel32 =3D 0 then
result =3D message_box(sprintf( "%s", { "Required dll: kernel32 not =
found . . ." } ), "Get Drives", MB_ICONERROR+MB_TASKMODAL )
abort(-1)
end if
GetDrives =3D define_c_func(kernel32, "GetLogicalDriveStringsA",{C_INT, =
C_POINTER}, C_INT)
ptr =3D allocate_string( " =

if length then
result =3D message_box(sprintf( "\"%s\"", { peek4s( {ptr, length} ) } =

else
