If an output parameter with type STR or WSTR is defined as a Null string only a maximum 65536 string will be return.Novice Windows programmers can often think that DllMain is a good place to get that one-time set-up and tear-down work done. Otherwise an array is returned that contains the function return value and a copy of all the parameters (including parameters that the function may have modified when passed by reference). If the function call fails then is set to non-zero. To call the unicode version use MessageBoxW. MessageBoxA is attempted when MessageBox is given as the function name. To use the 'cdecl' method place ':cdecl' after the return type.ĭllCall("SQLite.dll", "int:cdecl", "sqlite3_open", "str", $sDatabase_Filename, "long*", 0).īy default, AutoIt tries to use the ANSI version of a function name, i.e. If you want to manually control the loading and unloading of the DLL then you should use DllOpen() and DllClose() and use a handle instead of a filename in this function.īy default, AutoIt uses the 'stdcall' calling method.
If a dll filename is given then the DLL is automatically loaded and then closed at the end of the call. Sets the flag to = unable to use the DLL file,ģ = "function" not found in the DLL file, The first two long values correspond to the first POINT structure and the second two values correspond to the second POINT structure. For example, a structure containing 2 POINT structures ("long long") would be declared as "long long long long". To use nested structures inside a structure you must re-define the nested structure. For example "int*" passes a pointer to an "int" type.Ĭonversions from Windows API types to AutoIt types: No value (only valid for return type - equivalent to void in C)Īn integer big enough to hold a pointer when running on x86 or 圆4 versions of AutoIt.Īn unsigned integer big enough to hold a pointer when running on x86 or 圆4 versions of AutoIt.Īn ANSI string (a minimum of 65536 chars is allocated).Ī UNICODE wide character string (a minimum of 65536 chars is allocated).Īdd * to the end of another type to pass it by reference.
