[edit] Explanation
Indicates that the function does not return.
This attribute applies to the name of the function and specifies that the function does not return by executing the return statement or by reaching the end of the function body (it may return by executing longjmp). The behavior is undefined if the function with this attribute actually returns. A compiler diagnostic is recommended if this can be detected.
It has been previously denoted by the keyword _Noreturn until it was deprecated since C23 and replaced by this attribute.
[edit] Standard library
The following standard functions are declared with noreturn attribute (they used to be declared with _Noreturn specifier until C23):
