By Stephen R. The switch statement in C is a control statement that is useful in a limited number of cases. The switch statement resembles a compound if statement by including a number of different possibilities rather than a single test. All C streams (open with functions in ) are closed (and flushed, if buffered), and all files created with tmpfile are removed. Control is returned to the host environment. Note that objects with automatic storage are not destroyed by calling exit (C).

Dec 13, 2019 This is especially useful for C cross-platform developers because you can target a container that runs a different operating system than the one on your development machine. In this blog post we’re going to use Visual Studio’s native CMake support to build a simple Linux application in a Linux docker container over SSH.

Causes normal program termination to occur.
Several cleanup steps are performed:
1) destructors of objects with static storage duration are called in reverse order of completion of their constructors or the completion of their dynamic initialization, and the functions passed to std::atexit are called in reverse order they are registered (last one first). a) any static objects whose initialization was completed before the call to std::atexit for some function F will be destroyed after the call to F during program termination. b) any static objects whose construction began after the call to std::atexit for some function F will be destroyed before the call to F during program termination (this includes the case where std::atexit was called from the constructor of the static object) |
1) The destructors of objects with thread local storage duration that are associated with the current thread, the destructors of objects with static storage duration, and the functions registered with std::atexit are executed concurrently, while maintaining the following guarantees: a) The last destructor for thread-local objects is sequenced-before the first destructor for a static object b) If the completion of the constructor or dynamic initialization for thread-local or static object A was sequenced-before thread-local or static object B, the completion of the destruction of B is sequenced-before the start of the destruction of A c) If the completion of the initialization of a static object A was sequenced-before the call to std::atexit for some function F, the call to F during termination is sequenced-before the start of the destruction of A d) If the call to std::atexit for some function F was sequenced-before the completion of initialization of a static object A, the start of the destruction of A is sequenced-before the call to F during termination. e) If a call to std::atexit for some function F1 was sequenced-before the call to std::atexit for some function F2, then the call to F2 during termination is sequenced-before the call to F1 |
- In the above,
- if any function registered with
atexit
or any destructor of static/thread-local object throws an exception, std::terminate is called - if the compiler opted to lift dynamic initialization of an object to the static initialization phase of non-local initialization, the sequencing of destruction honors its would-be dynamic initialization.
- If a function-local (block-scope) static object was destroyed and then that function is called from the destructor of another static object and the control flow passes through the definition of that object (or if it is used indirectly, via pointer or reference), the behavior is undefined.
- if a function-local (block-scope) static object was initialized during construction of a subobject of a class or array, it is only destroyed after all subobjects of that class or all elements of that array were destroyed.
3) files created by std::tmpfile are removed
4) control is returned to the host environment. If
exit_code
is 0 or EXIT_SUCCESS, an implementation-defined status indicating successful termination is returned. If exit_code
is EXIT_FAILURE, an implementation-defined status indicating unsuccessful termination is returned. In other cases implementation-defined status value is returned.Stack is not unwound: destructors of variables with automatic storage duration are not called.
[edit]Relationship with the main function
Returning from the main function, either by a
return
statement or by reaching the end of the function performs the normal function termination (calls the destructors of the variables with automatic storage durations) and then executes std::exit
, passing the argument of the return statement (or 0 if implicit return was used) as exit_code

Dev C++ Code
Which library does a Dev-C++ compiled program have to link with to resolve the following [Linker error]:
undefined reference to '[email protected]'
ld returned 1 exit status
when WinMain is clearly defined in the C++ source code as the name of main, using the Dev-C++ environment v4.9.9.2. and #include <windows.h>, i.e.:
#include <windows.h>
...
void WinMain()
{
...
}
On Unix I used to run a piped command like:
cat lib*.a | ??? | gawk 'WinMain'
well, maybe I ran a script that fed the list of libraries in one at a time to the middle command or something like that, in order to find an interface like 'WinMain' in a library, but do not see anyway of doing the same on WinXP hosting the Dev-C++ environment.
Also, obviously, I've been away from Unix too long to remember the middle command. Duh?
