The memcpy() function copies count bytes of src to dest. The behavior is undefined if copying takes place between objects that overlap. The memmove() function allows copying between objects that might overlap. Return Value. The memcpy() function returns a pointer to dest. Example that uses memcpy() This example copies the contents of source to
Apr 21, 2014 · But for the example you give, it doesn't matter - if it's going to fail, it will be in the initial strlen, so strncpy doesn't buy you anything in terms of safety (and presumbly strncpy is slower as it has to both check bounds and for nul), and any difference between memcpy and strcpy isn't worth changing code for speculatively.
If copying takes place between objects that overlap, the behavior is undefined. This example demonstrates the difference between &strcpy. memcpy() — Copy
Memcpy simply copies data one by one from one location to another while memmove copies data first to an intermediate buffer, then from buffer to destination. Memcpy doesn't check for overflow or \0 (null terminator) Memcpy leads to to problems when source and destination addresses overlap. With memcpy, the destination cannot overlap the source

Oct 25, 2015 · *) The main difference between memcpy and memmove is,memcpy works on the same string but memmove works in separate memory by taking a copy of the string. *) Due to this,overlapping happens in memcpy not in memmove Let me explain you with an example. I took a character array : char s[20]="alightechs"; if i do the following operations separately,
