[HELP] reclocating a buffer

Hello im a little stumped on how i can relocate a buffer once its been signed...

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 );

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....

realloc ;D

realloc - C++ Reference

so would this work...

Code:

Buffer = (char*) realloc (Buffer, - sizeof header );

so this should relloc the buffer and minus the header?

Code:

Buffer = (char*) realloc ((void*)&Buffer[2], sizeof Buffer - sizeof header );

I guess that should work

i found it easyier to do this method instead....

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;

Cleaner and better mabye?
