Questions tagged [unpack]
A function in several scripting languages for unpacking binary data into native types for the language in question. The opposite of the 'pack' function. For the Python concept, use 'iterable-unpacking'. This tag should be used with a programming language tag as well. While also used as directive or pragma in some compilers to ignore standard variable alignment for data aggregates (i.e. struct), do not use this tag for posts on that subject.
