tst_memcpy.c

KEILC51程序实例和配套硬件目标板,很详细,程序有注释

#include <string.h>
#include <stdio.h>                  /* for printf */
void tst_memcpy (void) {
   static char src1 [100] ="Copy this string to dst1";
   static char dst1 [100];
   char *p;
   p = memcpy (dst1, src1, sizeof (dst1));
   printf ("dst = \"%s\"\n", p);
