Synopsis:

#include <string.h>
void *memcpy( void *dst,
              const void *src,
              size_t length );
void __far *_fmemcpy( void __far *dst,
                      const void __far *src,
                      size_t length );

Description:

The memcpy function copies length characters from the buffer pointed to by src into the buffer pointed to by dst.  Copying of overlapping objects is not guaranteed to work properly.  See the  memmove function if you wish to copy objects that overlap.

The _fmemcpy function is a data model independent form of the memcpy function.  It accepts far pointer arguments and returns a far pointer.  It is most useful in mixed memory model applications.

Returns:

The original value of dst is returned.

memchr, memcmp, memicmp, memmove, memset

Example:

#include <stdio.h>
#include <string.h>

void main()
  {
    auto char buffer[80];

    memcpy( buffer, "Hello", 5 );
    buffer[5] = '\0';
    printf( "%s\n", buffer );
  }

memcpy is ANSI, _fmemcpy is not ANSI
