In C, typedef is considered as a storage class like other storage classes (auto, register, static and extern), nevertheless the purpose of typedef is to assign alternative names to existing types. You signed out in another tab or window. Any of the following names declared at namespace scope have internal linkage variables, functions, or function templates declared static non-volatile non-inline (since C++17) const-qualified variables (including constexpr) that aren't declared extern However, GCC allows 'auto', perhaps with 'inline', to support nested functions. */ - if (specbits & (1 << (int) RID_AUTO)) + if (storage_class == csc_auto) { if (pedantic) pedwarn ("invalid storage

The object is allocated when the thread begins and deallocated when the thread ends. share|improve this answer edited Dec 29 '11 at 22:59 answered Dec 29 '11 at 22:32 Michael Burr 239k30352573 add a comment| up vote 1 down vote You can't do that -- In part it's a grammatical convenience, but it is deliberate that you can either have typedef or one of the more "obvious" storage class specifiers. Note: usual implementations of this feature use variants of the double-checked locking pattern, which reduces runtime overhead for already-initialized local statics to a single non-atomic boolean comparison. (since C++11) The destructor

I've compiled that code: [code] static __forceinline int f(void) { return 1; } int main() { int i = f(); return 0; } [/code] with gcc: torri:~/code: ~/local/opt/mingw-w64-x86_32/bin/i686-w64-mingw32-gcc -o forceinline forceinline.c The object is allocated at the beginning of the enclosing code block and deallocated at the end. In a declaration static int x; the type of x is int. Geeksforgeeks

The name can be referred to from all scopes in the current translation unit. I'd imagine it's because "static int" isn't a type in the same way "volatile int" is. is `bar()` static? { return foo(); } Note that is you use the preprocessor to get the 'static typedef' effect, that would make bar() a static function. The object is allocated and deallocated per request by using dynamic memory allocation functions. [edit] Linkage A name that denotes object, reference, function, type, template, namespace, or value, may have linkage.

If a name has linkage, it refers to the same entity as the same name introduced by a declaration in another scope.

A typedef declaration creates an alias for a type. It indicates automatic storage duration, which is the default for these kinds of declarations. The removed testcases pr14289-2.c and pr14289-3.c only differ from pr14289-1.c in that they include multiple storage class specifiers on a single declaration. Big conflict here so the compiler generates an error.

All local objects have this storage duration, except those declared static, extern or thread_local.
