## bcopy ##
拷贝内存内容
### 相关函数 ###
memccpy,memcpy,memmove,strcpy,ctrncpy
### 表头文件 ###
```
#include <string.h>
```
### 定义函数 ###
```
void bcopy(const void *src, void *dest, int n);
```
### 函数说明 ###
bcopy()与memcpy()一样都是用来拷贝src所指的内存内容前n个字节到dest所指的地址,不过参数src与dest在传给函数时是相反的位置。
### 附加说明 ###
建议使用memcpy()取代
### 范例 ###
```
#include<string.h>
main()
{
char dest[30]=”string(a)”;
char src[30]=”string\0string”;
int i;
bcopy(src,dest,30);/* src指针放在前*/
printf(bcopy(): “)
for(i=0;i<30;i++)
printf(“%c”,dest[i]);
memcpy(dest src,30); /*dest指针放在钱*/
printf(‘\nmemcpy() : “);
for(i=0;i<30;i++)
printf(“%c”,dest[i]);
```
### 执行 ###
```
bcopy() : string string
memcpy() :string sring
