4.7 – Handling Yields in C 在内部,Lua 使用C longjmp工具来产生协程。因此,如果一个C函数foo调用一个API函数并且这个API函数产生(通过调用另一个产生的函数直接或间接产生),Lua不能再返回foo,因为longjmp它从C栈中移除了它的框架。 为了避免这样的问题,提出的Lua每当它试图跨越API调用来产生,除了三个功能错误:...
In this program, the elements are stored in the integer array data[]. Then, the elements of the array are accessed using the pointer notation. By the way, data[0] is equivalent to *data and &data[0] is equivalent to data data[1] is equivalent to *(data + 1) and &data[1] is ...
