and shows bad pointer. what should i do to remove this error.
i need help urgently

BYTE *bRecievedData; /* buffer for reciving data */

memset(bRecievedData,0,sizeof(bRecievedData));

You should probably allocate memory for it before calling memset(). Is bReceivedData a single BYTE or and array or BYTEs?

it is a single byte

hi i have solved it. it is just because of pointer. it should be assigned to NULL

Actually, you still need to allocate memory for it. It might "appear" to work, but it is not correct. Try this:

CPP / C++ / C Code:

BYTE *bRecievedData; /* buffer for reciving data */
bRecievedData = new BYTE;
memset(bRecievedData,0,sizeof(bRecievedData));
