这是《Keil Cx51 V7.0单片机高级语言编程与uVision2应用实践》教材各章中列出的全部程序例子。

#include <stdlib.h>
#include <stdio.h>                    /* for printf */
void tst_malloc (void) {
   unsigned char xdata *p;
   p = malloc (1000);                 /* allocate 1000 bytes */
   if (p == NULL)
      printf ("Not enough memory space\n");
   else
      printf ("Memory allocated\n");
}
