MSDN中memset函数说明的翻译

MSDN举的memset函数的例子：

#include <memory.h>
#include <stdio.h>

int main( void )
{
   char buffer[] = "This is a test of the memset function";

   printf( "Before: %s/n", buffer );
   memset( buffer, '*', 4 );
   printf( "After:  %s/n", buffer );
}
Output//输出结果如下
Before: This is a test of the memset function
After:  **** is a test of the memset function

 

 

函数原型：

void *memset( void * dest , int c , size_t count );

memsetMSDN的解释及翻译：

Sets the first count chars of dest to the character c  把dest最开头的几个字符更换为count个c对应的字符

Security Note    Make sure that the destination buffer is the same size or larger than the source buffer.//确定目标字符串的长度和源字符串更长或相同
