PUREBASIC CLEARSTRUCTURE CODE
Keywords to reduce the amount of code to type and ease its readability. When using a lot of structure fields you can use the With : EndWith Seen as an oddity (and to be honest, it is) but it's like that since the very start of PureBasic and many, many sources rely When using pointers in structures, the '*' has to be omitted when using the field, once more to ease API code porting. This means that a willĪllocate an array from 0 to 1 where Dim a (2 ) will allocate an array from 0 to 2. To be conform to the C/C++ structure format (to allow direct API structure porting). Please note, that in structures a static array doesn't behave like the normal BASIC array (defined using Dim) SizeOf can be used with structures to get the size of the structure and OffsetOf can be used to retrieve The special value #PB_Structure_AlignC can be used to align the structureĪs it would be done in language C, useful when importing C structures to use with API functions. It can help to get more performance while accessing structure fields, but it can use more memory, as some spaceīetween each fields will be wasted. For example, if the alignment is set to 4, every field offset will be on a 4 byte boundary. The optional Align parameter allows to adjust alignment between every structure field. This is useful to do basic inheritance of structures.įor advanced users only. All fieldsįound in the extended structure will be available in the new structure and will be placed before The optional Extends parameter allows to extends another structure with new fields.
PUREBASIC CLEARSTRUCTURE FULL
It's possible to perform a full structure copy by using the equal affectation between two structure element of the same type. It is also possible to initialize a structure in memory withĬlearStructure() and reinitialize it with
PUREBASIC CLEARSTRUCTURE FREE
Memory structure with AllocateStructure() and free it with FreeStructure(). However, advanced users will be able to allocate a Generally, structures are used in association with a variable, an To declare such field, use the following keywords:
When the object using the structure is created. Integer (.i), Float (.f ), Quad (.q), Double (.d)), String (.s) and Fixed String (.s).ĭynamic objects like arrays, lists and maps are also supported inside structure and are automatically initialized Structure fields must have an explicit type among all Basic Types supportedīy PureBasic, i.e. Statics arrays are supported inside structures. Structures fields are accessed with the \ option. It is very useful as you can group into the same To enable faster and easier handling of data files. Structure is useful to define user type, and access some OS memory areas.
