Thread: Inserting hex byte into a data

URGENT: NEED HELP

I have this situation where I need to insert hex byte type into a data, but my code doesn't work out as expected, that it only worked once. This is how the problem:

E.g.:

unsigned char data[10] = "\x50\x10\x30\x20\x17\x9A\x00\x10";

//insert and produce "\x50\x10\x10\x30\x20\x17\x9A\x00\x10\x10"

I have used loop to do so, but it only applicable to insert once, but not twice or more. Searching for any opinions and alternatives. Please reply. Thanks.

Code:

void main(){

       int i, j=0;
       BYTE dataBuf[20] = "\x90\x50\x80\x10\x10\x90\x10\x99\x1A"; //3,4,6
       BYTE cBuf[10]; //counter
       BYTE sBuf[20],outBuf[20]; 

       for(i=0; i<9; i++)
	{
	       if (bBuf[i] == 0x10){
                   cBuf[j] = i;     //using reference index
                   j++;  		
               }
	}

       memcpy(sBuf, dataBuf,sizeof(sBuf));
       for(i=0; i<j; i++)
	{	        			
		memcpy(&sBuf[cBuf[i]], &bBuf[cBuf[i]-1], sizeof(sBuf));				
	} 
        
}

The problem is fixed. Thanks.
