std::basic_syncbuf::emit(3)

💖 NAME 💖

std::basic_syncbuf::emit — okay so this is literally the page for std::basic_syncbuf::emit, bestie. And up top we're in the C++ Standard Libary manual (that spelling is straight from the header, iykyk 😭💅).

✨ Synopsis ✨

bool emit();

Atomically transmits all pending output to the wrapped stream. Periodt.

All emit() calls transferring characters to the same wrapped stream buffer object appear to execute in a total order, where each emit() call synchronizes-with subsequent emit() calls in that total order, even if these calls are made through difference instances (yes, literally the word on the page, bestie 😭) of std::basic_syncbuf/std::basic_osyncstream. In practice, this means that emit() takes a lock uniquely associated with the wrapped stream object: for example, it could be held in a static hash map where the address of the wrapped stream is used as the key. No cap, that's the synchronization vibe.

If a call had been made to sync since the last call to emit(), then it also flushes the wrapped stream by calling pubsync() on it.

🎀 Parameters 🎀

(none) — literally none, not a single parameter. Slay.

🌸 Return value 🌸

true if all of the following is true:

• there is a wrapped stream (the wrapped streambuf pointer is not null)
• all characters from the temporary storage were successfully sent into the wrapped stream
• the call to pubsync(), if requested, also completed successfully.

Returns false otherwise.

🦋 Notes 🦋

Normally called by the destructor or move assignment of the owning std::basic_osyncstream, or by std::basic_osyncstream::emit.

• destructor — destroys the basic_osyncstream and emits its internal buffer (public member function of std::basic_osyncstream<CharT,Traits,Allocator>)
• emit — calls emit() on the underlying basic_syncbuf to transmit its internal data to the final destination (public member function of std::basic_osyncstream<CharT,Traits,Allocator>)
• constructor — constructs a basic_syncbuf object (public member function)
