The vector data type names defined in Built-in Vector Data Types, but The data type names described in the following table are reserved and cannot ![]() These flags are described in detail in the This is a bitfield and can be 0 or a combination of the following This can be used to identify async copies from This opaque type is used to identify the reservation for The N-dimensional range over which a kernel executes.Ī device side event that identifies a command enqueue to This queue can only be used to enqueue commands from kernels executing Other Built-in Data TypesĪ 1D image created from a buffer object 6. The following table describes the list of additional data types supported by The void type comprises an empty set of values it is an incomplete Pointer to void, and the result will compare equal to the original To void can be converted to this type, then converted back to To void, and the result will compare equal to the original pointer.Īn unsigned integer type 3 with the property that any valid pointer ![]() Void can be converted to this type, then converted back to pointer The unsigned integer type 3 of the result of the sizeof operator.Ī signed integer type 3 that is the result of subtracting twoĪ signed integer type 3 with the property that any valid pointer to The half data type must conform to the IEEE 754-2008 half precision The double data type must conform to the IEEE 754 double precision The float data type must conform to the IEEE 754 single precision The value true expands to the integer constant 1 and the valueĪ signed two’s complement 16-bit integer.Ī signed two’s complement 32-bit integer.Ī signed two’s complement 64-bit integer. Built-in Scalar Data TypesĪ conditional data type which is either true or false. The following table describes the list of built-in scalar data types. Conversion rules for sRGBA and sBGRA images Conversion rules for signed and unsigned 8-bit, 16-bit and 32-bit integer channel data types Conversion rules for floating-point channel data type Conversion rules for half precision floating-point channel data type ![]() Conversion rules for normalized integer channel data types Async Copies from Global to Local Memory, Local to Global Memory, and Prefetch Specifying Attributes of Blocks and Control-Flow-Statements So it's now a collection of smart pointers which will automatically delete your PoolItem pointers on destruction of the container, or when they are removed from the container.Ĭhange line 27 to be returning a reference - because you know it's never nullptr. You should be using smart pointers, which will handle the memory management for you, and that will fix everything.Ĭhange line 35 to be: std::multimap> _usedPool There's another important question - who is deleting those PoolItem*s in the collection you reference on line 35? Then you try to return your temporary - but that isn't the one you want to point to! Then you insert it into your pool - so you've made a copy of this item and it's in _usedPool. ReserveNewItem has a serious logical error there. Help!įirst, thanks for a very clear formatting and statement of the problem! It made it really easy to debug. In MSVC 2015, this fails to compile with an 'illegal indirection' error on the return line- i worry that there's more that i'm missing as well. Without further ado, the MWE: struct PoolItem I'm getting an 'illegal indirection' compile error during the return of the reserveNewItem(.) function, and am having trouble understanding why as well as what to place instead (nothing i tried works). One of the class members reserves a new item and stores its' pointer in a used/unused pool to be reused later (if available). Hey there, I am trying to create a memory pool because the application i'm making reallocates hundreds of (large) things it doesn't need to.
