- Rename D3D12Enum.h to D3D12Enums.h for naming consistency - Fix OpenGL unit test GLAD initialization by using gladLoadGL() instead of gladLoadGLLoader(wglGetProcAddress) for fallback support - Migrate remaining tests to use gtest_discover_tests for granular test discovery (math, core, containers, memory, threading, debug, components, scene, resources, input, opengl) - Remove obsolete TEST_RESOURCES_DIR and copy_directory commands from OpenGL unit test CMakeLists (minimal/Res doesn't exist) - Update TEST_SPEC.md with performance metrics and per-module build/test commands for faster development workflow - Update CMake path references to use lowercase paths

# Mutex::lock
|
||
|
||
```cpp
|
||
void lock() const;
|
||
```
|
||
|
||
获取互斥锁(const 版本)。如果锁已被其他线程持有,则阻塞当前线程直到锁可用。
|
||
|
||
该方法是 `std::lockable` 接口的实现,可与 `std::lock_guard`、`std::unique_lock` 等 RAII 工具配合使用。
|
||
|
||
**参数:** 无
|
||
|
||
**返回:** 无
|
||
|
||
**线程安全:** ✅
|
||
|
||
**复杂度:** 平均 O(1),最坏情况 O(n),n 为竞争线程数
|
||
|
||
**示例:**
|
||
|
||
```cpp
|
||
#include "XCEngine/Threading/Mutex.h"
|
||
#include <mutex>
|
||
|
||
XCEngine::XCEngine::Threading::Mutex mtx;
|
||
int counter = 0;
|
||
|
||
void Increment() {
|
||
mtx.lock();
|
||
++counter;
|
||
mtx.unlock();
|
||
}
|
||
|
||
// 使用 RAII 自动管理锁
|
||
void SafeIncrement() {
|
||
std::lock_guard<XCEngine::Threading::Mutex> guard(mtx);
|
||
++counter;
|
||
}
|
||
```
