Fixed buffer
WebAug 26, 2024 · Fixed size buffer fields are struct members available in unsafe contexts that represent C style in-line arrays. Such fields are rare beasts and primarily used for interoperation with native code. Let’s take a look at how they are declared. public unsafe struct MyBufferWrapper { Perhaps the most common version of the circular buffer uses 8-bit bytes as elements. Some implementations of the circular buffer use fixed-length elements that are bigger than 8-bit bytes—16-bit integers for audio buffers, 53-byte ATM cells for telecom buffers, etc. Each item is contiguous and has the correct data alignment, so software reading and writing these values can be faster than software that handles non-contiguous and non-aligned values.
