RESERVEDDATATYPES(3clc)

✨ RESERVED DATA TYPES ✨

okay bestie, welcome to the OpenCL Manual 💖 this one is the reserved data types page, and it's short but important — these are the names you are NOT allowed to claim as your own. no cap.

---

🌸 NAME 🌸

Reserved_Data_Types — Built-in reserved Data Types. 💅

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie: every single data type name in the list below is reserved. that means you literally cannot use them as user-defined type names in your application. they're taken. they're booked. they're the main characters and you are not casting them. 👑

and it gets deeper — the vector data type names defined over in vectorDataTypes(3clc) are also reserved whenever n is any value other than 2, 3, 4, 8 and 16. so like, the whole n-situation is off-limits unless it's one of those five numbers. iykyk. ✨

here's the full rundown, one by one:

• booln — a boolean vector. 🍓
• halfn — a 16-bit float vector.
• quad, quadn — a 128-bit floating-point number and vectors.
• complex half, complex halfn, imaginary half, imaginary halfn — complex and imaginary 16-bit floating-point scalar and vector. 💜
• complex float, complex floatn, imaginary float, imaginary floatn — complex and imaginary 32-bit floating-point scalar and vector.
• complex double, complex doublen, imaginary double, imaginary doublen — complex and imaginary 64-bit floating-point scalar and vector.
• complex quad, complex quadn, imaginary quad, imaginary quadn — complex and imaginary 128-bit floating-point scalar and vector. 🌈
• floatnxm — an n x m matrix of single precision floating-point values stored in column-major order. ✨
• doublenxm — an n x m matrix of double precision floating-point values stored in column-major order.
• long double, long doublen — a floating-point scalar and vector type with at least as much precision and range as a double and no more precision and range than a quad. 🫶
• long long, long longn — a 128-bit signed integer scalar and vector. 🔥
• unsigned long long, ulong long, ulong longn — a 128-bit unsigned integer scalar and vector. 🔥

bestie, this is not a suggestion list. it's a do-not-touch list. pick a different name or the compiler will simply not have it. 💀

okay that's the whole page, bestie, you ate it 💅🫶 this was the OpenCL Manual reserved data types situation, brought to you by The Khronos Group, dated 01/14/2021. now go pick a type name that isn't on the forbidden list, mwah 💖🌸
