what is the algorithim for the prototype function.

/* The offset & length are in terms of bits..
the fourth parameter is a value which is to be stored in char pointer that is pData
*/
void putBits(char*pData , int offset , int length , int value )
{
}

int main()
{
char *pData = new char[90];

putBits(pData , 9 , 13 , 200);

}
