Difference between WIN32 memory macros vs cstring memory operations?

Question

Memory block operations in c, such as memcpy, allow for optimised operations for moving or clearing blocks of memory. I have recently discovered that the WIN32 API provides macros supporting similar if not identical features, such as ZeroMemory. I do not know the difference and wish to find out. http://msdn.microsoft.com/en-us/library/windows/desktop/aa366920(v=vs.85).aspx

Answer 1

ZeroMemory是一个调用memset的宏， CopyMemory是一个调用memcpy的宏，等等。所以，根本没有区别。
