According to the manual, passing -std=gnu11 enables C99 instead of GNU inline semantics. This means inline, static inline and extern inline all behave differently. In particular, inline expects an external definition in a separate translation unit (which you can provide without duplicating the definition – see this answer).
In C++ it is not legal to call the main function in your code, so there’d be no way it could ever be inlined.
Yes. From documentation v4.1.2 From documentation latest always_inline Generally, functions are not inlined unless optimization is specified. For functions declared inline, this attribute inlines the function even if no optimization level was specified.
A C code can be optimized in two ways: For Code size and for Execution Time. inline functions: gcc.gnu.org says, By declaring a function inline, you can direct GCC to make calls to that function faster. One way GCC can achieve this is to integrate that function’s code into the code for its callers. This … Read more
inline is the keyword, in C++ and C99. __inline is a vendor-specific keyword (e.g. MSVC) for inline function in C, since C89 doesn’t have it. __inline__ is similar to __inline but is from another set of compilers. __forceinline is another vendor-specific (mainly MSVC) keyword, which will apply more force to inline the function than the … Read more
As example (DEMO): HTML: <div class=”header”> <img src=”https://stackoverflow.com/questions/11701311/img/logo.png” alt=”logo” /> <h1>My website name</h1> </div> CSS: .header img { float: left; width: 100px; height: 100px; background: #555; } .header h1 { position: relative; top: 18px; left: 10px; } DEMO
The inline keyword indicates that a function definition should be inserted inline into any code which uses it. Most of the time, this will not have any effect on the type of the function. However, in rare cases, it can lead to a function which has a more general type, since there are constraints which … Read more
Quoting from C++ FAQ: Note: It’s imperative that the function’s definition (the part between the {…}) be placed in a header file, unless the function is used only in a single .cpp file. In particular, if you put the inline function’s definition into a .cpp file and you call it from some other .cpp file, … Read more
The former (using inline) allows you to put that function in a header file, where it can be included in multiple source files. Using inline makes the identifier in file scope, much like declaring it static. Without using inline, you would get a multiple symbol definition error from the linker. Of course, this is in … Read more
Used request instance as temporary container for obj. Overrided Inline method formfield_for_foreignkey to modify queryset. This works at least on django 1.2.3. class RoomInline(admin.TabularInline): model = Room def formfield_for_foreignkey(self, db_field, request=None, **kwargs): field = super(RoomInline, self).formfield_for_foreignkey(db_field, request, **kwargs) if db_field.name == ‘inside_room’: if request._obj_ is not None: field.queryset = field.queryset.filter(building__exact = request._obj_) else: field.queryset = … Read more
