木头云 c9d0a94894 refactor(uninitialized): Improve construct() overload resolution IMPROVEMENTS: 1. Add explicit zero-argument overload to avoid SFINAE ambiguity 2. Require at least one argument (A1) for parameterized overloads 3. Better separation between direct initialization and aggregate initialization BENEFITS: - Clearer intent: zero-argument construction is explicitly handled - Avoids potential SFINAE ambiguity when empty parameter pack is used - More maintainable: easier to understand which overload is selected - Consistent with modern C++ best practices for variadic templates TECHNICAL DETAILS: - Zero-arg overload: Always uses T() for value initialization - One-or-more-arg overload: Uses SFINAE to choose between: * T(args...) for types with matching constructor * T{args...} for aggregate types or types with initializer_list ctor This is a code quality improvement and does not fix any compilation issues, but provides better template overload resolution.		2025-12-03 08:13:44 +00:00

cpp-ipc (libipc) - C++ IPC Library

A high-performance inter-process communication library using shared memory on Linux/Windows.

Compilers with C++17 support are recommended (msvc-2017/gcc-7/clang-4)
No other dependencies except STL.
Only lock-free or lightweight spin-lock is used.
Circular array is used as the underline data structure.
ipc::route supports single write and multiple read. ipc::channel supports multiple read and write. (Note: currently, a channel supports up to 32 receivers, but there is no such a limit for the sender.)
Broadcasting is used by default, but user can choose any read/ write combinations.
No long time blind wait. (Semaphore will be used after a certain number of retries.)
Vcpkg way of installation is supported. E.g. vcpkg install cpp-ipc

Reference

使用共享内存的跨平台（Linux/Windows，x86/x64/ARM）高性能IPC通讯库

推荐支持C++17的编译器（msvc-2017/gcc-7/clang-4）
除STL外，无其他依赖
无锁（lock-free）或轻量级spin-lock
底层数据结构为循环数组（circular array）
ipc::route支持单写多读，ipc::channel支持多写多读【注意：目前同一条通道最多支持32个receiver，sender无限制】
默认采用广播模式收发数据，支持用户任意选择读写方案
不会长时间忙等（重试一定次数后会使用信号量进行等待），支持超时
支持Vcpkg方式安装，如vcpkg install cpp-ipc
