WebOct 25, 2016 · Bit-fields are typically only used when there's a need to map structure fields to specific bit slices, where some hardware will be interpreting the raw bits. An example might be assembling an IP packet header. I can't see a compelling reason for an emulator to model a register using bit-fields, as it's never going to touch real hardware!

WebAs far as I understand, bitfields are purely compiler constructs And that's part of the problem. If the use of bit-fields was restricted to what the compiler 'owned', then how the compiler packed bits or ordered them would be of pretty much no concern to anyone. WebJun 29, 2011 · Bit-fields in unions behave in the same way they behave anywhere else. There's nothing special about bit-fields in unions (or unions with bit-fields). Yes it is possible, but I would recommend against it. The length and packing of bitfields is not portable. The size of the union will be difficult to predict (see here ).
WebAug 28, 2015 · Bit fields are defined just like structures, which means they make for very easy to read code. The disadvantage to bit fields is that they are non-portable. Using bit fields means placing a lot of... WebJul 30, 2024 · A bit field can hold more than a single bit; for example, if you need a variable to store a value from 0 to 7, then you can define a bit field with a width of 3 bits as follows −. struct { unsigned int age : 3; } Age; The above structure definition instructs the C compiler that the age variable is going to use only 3 bits to store the value.
WebJan 26, 2013 · The smallest addressable "thing" in a C Program is a byte or char. A char is at least 8 bits long. So you cannot have a type (or objects of any type) with less than 8 bits. What you can do is have a type for which objects occupy at least as many bits as a char and ignore most of the bits

In practice, you can use sizeof (bool) * CHAR_BIT as your guide to knowing how many bits are available. From C++98, § 9.6.3. A bit-field shall have integral or enumeration type (3.9.1). From C++98, § 3.9.1.7. Types bool, char, wchar_t, and the signed and unsigned integer types are collectively called integral types. cannery pier hotel discountWebIn programming terminology, a bit field is a data structure that allows the programmer to allocate memory to structures and unions in bits in order to utilize computer memory in an efficient manner.
