c++ Programming Glossary: memmoveWhat is the difference between memmove and memcpy? http://stackoverflow.com/questions/1201319/what-is-the-difference-between-memmove-and-memcpy is the difference between memmove and memcpy What is the difference between memmove and memcpy.. between memmove and memcpy What is the difference between memmove and memcpy Which one do you usually use and how c c share.. the destination cannot overlap the source at all. With memmove it can. This means that memmove might be very slightly slower..

Which one to use - memmove() or memcpy() - when buffers don't overlap? http://stackoverflow.com/questions/1960991/which-one-to-use-memmove-or-memcpy-when-buffers-dont-overlap one to use memmove or memcpy when buffers don't overlap Using memcpy when source.. can lead to undefined behaviour in those cases only memmove can be used. But what if I know for sure buffers don't overlap.. there a reason to use specifically memcpy or specifically memmove Which should I use and why c c memory share improve this..

How are C array members handled in copy control functions? http://stackoverflow.com/questions/4164279/how-are-c-array-members-handled-in-copy-control-functions it involve std copy or std uninitialized_copy or memcpy or memmove or what c arrays copy constructor assignment operator share..
How can I elide a call if an edge condition is known at compile time? http://stackoverflow.com/questions/7658060/how-can-i-elide-a-call-if-an-edge-condition-is-known-at-compile-time a huge set of templates like std vector that will call memmove to move parts of array. Sometimes they will want to move parts.. the compiler is aware yet the compiler will still emit a memmove call. So basically I could have a wrapper inline void callMemmove.. void dest const void source size_t count if count 0 memmove dest source count but this would introduce an extra runtime..
Why is memcpy() and memmove() faster than pointer increments? http://stackoverflow.com/questions/7776085/why-is-memcpy-and-memmove-faster-than-pointer-increments is memcpy and memmove faster than pointer increments I am copying N bytes from pSrc.. int i 0 i N i pDest pSrc Why is this slower than memcpy or memmove What tricks do they use to speed it up c c loops share improve..
