unsigned char类型的数据如何赋值？？？
unsigned char databuf[255];
然后如何给databuf赋值，我用_mbscpy，这个函数的第二个参数该如何写？？

unsigned char databuf[255];
然后如何给databuf赋值，我用_mbscpy，这个函数的第二个参数该如何写？？
For example:
int i;
int In[255]
unsigned char databuf[255];
for(i=0; i<255; i++)
{
In[i]=i;
}
for(i=0; i<255; i++)
{
databuf[i]=(unsigned char)(In[i])
}
//////记住：In[i]的数值不能超过255！！！否则会失去高位BIT数

用strcpy编译会出错的。

_mbscpy(databuf, (unsigned char*)"XXXXXXXXX");

strcpy也可以呀。
unsigned char databuf[255];
strcpy(databuf,"abcdef");
unsigned char databuf[255];
strcpy(databuf,"abcdef");

同意楼上的朋友意见。

unsigned char a[4] = {'1','2','3','4'}
unsigned char b[4];
//把a的内容copy给b
memcpy(b,a,4);
unsigned char b[4];
//把a的内容copy给b
memcpy(b,a,4);

请举个具体的例子

memcpy不行吗？

unsigned char *_mbscpy( unsigned char *strDestination, const unsigned char *strSource );
returns the destination string. No return value is reserved to indicate an error.
Parameters
strDestination
Destination string
strSource
Null-terminated source string
wcscpy and _mbscpy are wide-character and multibyte-character versions of strcpy. The arguments and return value of wcscpy are wide-character strings; those of _mbscpy are multibyte-character strings. These three functions behave identically otherwise.
unsigned char *_mbscpy( unsigned char *strDestination, const unsigned char *strSource );
returns the destination string. No return value is reserved to indicate an error.
Parameters

Destination string
strSource
Null-terminated source string
