.init_array:0001A673 DCB 0 .init_array:0001A673 ; .init_array ends 可以看到上面的代码中执行了我们所定义的函数,.init节就是_init函数的代码,而.init_array节是一个指针数组,每一项对应的是一块代码,可以做一系列的初始化操作。那么为什么.init节的代码先于.init_array节的代码执行呢?这个要看linker的...

ctypes exports the byref() function which is used to pass parameters by reference. The same effect can be achieved with the pointer() function, although pointer() does a lot more work since it constructs a real pointer object, so it is faster to use byref() if you don’t need the poi...

Condition variables allow threads to synchronize to a value of a shared resource. Typically, condition variables are used as a notification system between threads. The same pthread_t object cannot be used by multiple threads simultaneously. For multiple threads, an array ...

A correct way to hash an array of independent values, and which does not require pre-buffering, is to pass previous hash value as a seed value. This method may be as fast or faster than pre-buffering, especially if lengths of values in the array are not small. An additional 1-2 cycle...
