The difference between _cdecl and _stdcal and the function of extern “c
Article directory Purpose _stdcal _cdecl result dll extern “c” Replenish Purpose 1) Understand the difference between _cdecl and _stdcal under Windows, so that you can better use modified functions to make function calls. There are several calling methods, divided into C style and Pascal style. The overall difference. _cdecl (c/c++ default, supports variable parameter functions, […]
std::condition_variable condition variable and lock_guard, unique_lock
Used to block one thread, or block multiple threads at the same time, until another thread modifies the shared variable (condition) and notifies condition_variable. A thread that intentionally modifies a variable must Obtain std::mutex (often via std::lock_guard ) Modify while holding lock Perform notify_one or notify_all on std::condition_variable (no need to hold locks for notifications) […]

What is std::jthread Class jthread represents a single thread of execution.

C/C++ 11/14 rewrites a std::function<…> function template that supports safety and no multiple copies, supports Lambda λ and overloaded operator()(…) operator structure and C/C++ language Ordinary functions.
As the title of this article indicates, it was rewritten for optimization, and the solid-size BUFF buffer provided by the standard library std::function implementation was cut off because it is no longer necessary. The implementation copies the shared pointer. Reference, instead of needing to copy the BUFF and reconstruct it like the official version. If […]
