The compiler will automatically converts the strings to unicode when needed. We use the 'p-unicode' pseudotype for the string parameters, as MessageBoxW() is an unicode only function. This time PureBasic can't find it alone as the function name isn't the same than the one used by the symbol MsgBox(Window.i, Body$, Title$, Flags.i) As MessageBoxA(0, "Hello", "World") We don't specify the flags MsgBox(0, "Hello", "World 2", 0)Įxample: With pseudotypes Import "User32.lib" No need to use 'As' as PureBasic decorates the function correctly We also define the 'Flags' as optional, with a default value of 0 (when omitted) MessageBoxA(Window.i, Body$, Title$, Flags.i = 0) On 圆4, there is only one calling convention, so ImportC will behave the sames as Import. ![]() The pseudotypes can be used for the parameters, but not for the returned The function are not stdcall, the ImportC variant should be used instead. Should work for most of the functions which use the standard call convention (stdcall). The last parameters can have a default value (need to be a constantĮxpression), so if these parameters are omitted when the function is called, the default value will be used.īy default the imported function symbol is 'decorated' in the following way: That Unlike CallFunction(), it can deal with double, float and quad ![]() Sequence as it has some advantages: type checking is done, number of This feature can replace the OpenLibrary()/ CallFunction() In the imported file, so if an error occurs, it will be reported by the linker. The compiler doesn't check if the functions really exists Once declared, the imported functions are directly availableįor use in the program, like any other commands. Import : EndImport allows to easy declare external functions and variables fromĪ library (.lib) or an object (.obj) file.
