Copies a specified number of bytes from one object to another.

    Format

      #include  <string.h>

      void *memcpy  (void *dest, const void *source, size_t size);

1  –  Function Variants

    The memcpy function has variants named _memcpy32 and _memcpy64
    for use with 32-bit and 64-bit pointer sizes, respectively.

2  –  Arguments

 dest

    A pointer to the destination object.

 source

    A pointer to the source object.

 size

    The length of the object to be copied.

3  –  Description

    The memcpy function copies size bytes from the object pointed
    to by source to the object pointed to by dest; it does not check
    for the overflow of the receiving memory area (dest). Unlike the
    strcpy function, the memcpy function does not stop when a null
    character is encountered.

4  –  Return Value

    x                  The value of dest.
