The memcpy function in C copies the specified number of bytes from one memory location to another memory location regardless of the type of data stored. It is used to specify the range of characters which could not exceed the size of the source I was just going through an implementation of memcpy, to understand how it differs from using a loop. 13 a performance optimization of memcpy () on some platforms (including x86-64) included changing the order in which bytes were copied from src to dest. org's Newlib mirror with clang support for ARM baremetal - eblot/newlib Optimized implementations of various library functions for ARM architecture processors - optimized-routines/string/aarch64/memcpy. But I couldn't see any difference between using a loop rather than memcpy, as memcpy .

It is usually more efficient than strcpy, which must scan the data it copies or memmove, which must take precautions to handle overlapping Unofficial mirror of sourceware glibc repository. This repository contains high-performance implementations of memset and memcpy in assembly. Unofficial mirror of sourceware glibc repository. Please do not rely on this repo. The C library memcpy() function is also known as Copy Memory Block function / Memomy to Memory Copy. - openbsd/src First hit for memcpy source code c. If the source and destination regions overlap, the behavior of memcpy is undefined. 13 a performance optimization of memcpy () on some Read-only git conversion of OpenBSD's official CVS src repository.
