A Deep Dive into libgcc And libsupc++

According to the specifications of the C and the C++ programming languages, implementations of C and C++ can be classified into hosted ones and freestanding ones, depending on whether the implementation has access to functionalities that require operating system (OS) support, such as memory allocation and multi-threading. A hosted implementation has full access to these functionalities, and can provide the full range of features required by the language. A freestanding implementation, on the other hand, does not have access to any functionality that requires support from the execution environment. Such implementations are only required to provide a subset of the language features. Freestanding implementations are important when developing operating systems, the standard C library,

namerefs (introduced in bash 4.0) act as aliases for other variables

var=meow
declare -n ref=var

echo $ref  # prints meow

ref=moo
echo $var  # prints moo
