问
我在"D:\Program Files\ARM\ADSv1_2\Include"下面找到了一个stdio.h文件,它对对这个函数是这样说的:


extern int sprintf(char * /*s*/, const char * /*format*/, ...);
   /*
    * is equivalent to fprintf, except that the argument s specifies an array
    * into which the generated output is to be written, rather than to a
    * stream. A null character is written at the end of the characters written;
    * it is not counted as part of the returned sum.
    * Returns: the number of characters written to the array, not counting the
    *          terminating null character.
    */

我在引用的时候是这样的用的:


sprintf(string,"%4dvVin0",ADC_Data00);

没有问题!

但是我现在迫切想了解一下,它的具体源码是什么样的,有哪为大哥可以帮帮我?
答 1: re:        
为什么我AXD执行这条语句的时候会死在这里????当我停下来的时候,发现执行光标指在数据异常取指的地方!编译的时候,没有任何问题!


sprintf(str, "%4d mV VIN3", ADC_Data);//已经在头文件里包含了 stdio.h


我上午用的时候还没有问题呢?下午试的时候就出现了这问题!!!

求个位大哥,给个说法!??????
