 * The second IN parameter is a double-zero-terminated ASCII string list.
 * The first is the DLL name (.dll can be omitted),

 * On call for given HMODULE, returns false if one of entries is not available
 * HMODULE gets -1 on LoadLibraryA() failure.
 * The caller may set HMODULE manually, and then load the function pointers only.
