How to ensure proper Compare for Write Buffer and Read Buffer in C++

See more:

VisualC++

Hi,

In my C++ application, wherein, I am trying to allocate Buffer and Read the buffer allocated, and ensure Read SCSI() returns successfully(Good Status)

my Steps. 1. Write Some buffer check write buffer successfull assume 512 bytes
2. Read the same buffer written ensure ReadSCSI is successfull.
3. Ultimately ensure Write buffer and Read buffer comparison is identical,

I need a snippet of code(directly compares Write Buffer/Read Buffer without convolutions) where in Compare(Read/Write)buffer is same, if not otherwise throw an exception?

I am using VS2008 IDE, VC++ environment.(Windows 7 o/s).
