std::memcpy

Defined in header <cstring>
void* memcpy( void* dest, const void* src, std::size_t count );

Copies count characters from the object pointed to by src to the object pointed to by dest. If the objects overlap, the behavior is undefined. If the objects are not trivially copyable (scalars, arrays, C-compatible structs), the behavior is undefined.

Parameters

dest	-	pointer to the memory location to copy to
src	-	pointer to the memory location to copy from
count	-	number of bytes to copy

Return value

dest
