The `__noreturn` modifier can be placed immediately after a function type declaration to specify that
|
||
|
|
a function can never return. For example, the `exit` function is marked with `__noreturn`.
|
||
|
|
|
||
|
|
It is not necessary for functions that call `__noreturn` functions such as `exit` to explicitly specify
|
||
|
|
that they cannot return. The compiler will automatically determine that such functions are `__noreturn`.
|
||
|
|
This attribute is usually only necessary with functions that issue system calls that cause the
|
||
|
|
process to exit, or to transition to a new codebase (such as `execve`).
