[HELP] reclocating a buffer
Hello im a little stumped on how i can relocate a buffer once its been signed...
how could i go about being able to take way the header inside the buffer... (two bytes)
IF so example please....
what im trying to do is recv the entire buffer then minus the header....
Code:
// defined variables #define int recvd; #define unsigned Size; #define unsigned char* Buffer; #define MAX_RECEIVEPACKETLENGTH 0x4000 recvd = recv( sckSocket, (char*)Buffer, MAX_RECEIVEPACKETLENGTH , 0 ); Size = recvd; unsigned short header = GetWord( 0 );
IF so example please....
what im trying to do is recv the entire buffer then minus the header....
so would this work...
so this should relloc the buffer and minus the header?
Code:
Buffer = (char*) realloc (Buffer, - sizeof header );
Code:
Buffer = (char*) realloc ((void*)&Buffer[2], sizeof Buffer - sizeof header );
i found it easyier to do this method instead....
Cleaner and better mabye?
Code:
// defined variables #define int recvd; #define unsigned Size; #define unsigned char* Buffer; #define MAX_RECEIVEPACKETLENGTH 0x4000 recvd = recv( sckSocket, (char*)Buffer, MAX_RECEIVEPACKETLENGTH , 0 ); Size = recvd; unsigned char * decBuffer = new unsigned char[ Size - 2 ]; int m = Size - 2; // copy data from the DecBuffer to Buffer memcpy( decBuffer, Buffer + 2, sizeof( unsigned char ) * m ); // swap buffers delete [] Buffer; Buffer = decBuffer; Size = m;
