Detailed Description

Stand alone test of LTKC frame decoder and encoder, and XML encoder.

This is diagnostic 101 for the LLRP Tool Kit for C++ (LTKCPP).

DX101 reads an input file that contains consecutive LLRP frames, sometimes called the "binary encoding". Its output is printed on stdout.

For each input frame:

• Decode the frame into an LLRP message object
• Encode as XML text (essentially print) the message to stdout
• Encode the message into a separate frame buffer
• Compare the two frame buffers and make sure they are the same
• Destruct the LLRP message

This program can be tested using tools like valgrind (please see http://en.wikipedia.org/wiki/Valgrind) that detect memory leaks.

There are "golden" test files under the ../../Tests/dx101/ directory. Normal use is something like

dx101 ../../Tests/dx101/dx101_in.bin > dx101_out.tmp

Then to verify proper function, the output file is compared

cmp ../../Tests/dx101/dx101_out.txt dx101_out.tmp

When the files compare it means the dx101 and the LTKC are correct.

void dump (  unsigned char *  pBuffer, unsigned int  nBuffer )

Print a buffer in hex. And don't we always need one of these. 16 bytes per line extra space every four bytes full lines have a three digit sum, used to speed visually comparing entire lines. Parameters: [in]  pBuffer  Pointer to buffer [in]  nBuffer  Number of valid bytes in buffer Returns: none Definition at line 421 of file dx101.cpp. Referenced by main().

int main (  int  ac, char *  av[] )

Command main routine. Command synopsis: dx101 INPUTFILE 0 Everything *seemed* to work. 1 Bad usage 2 Could not open input file Definition at line 89 of file dx101.cpp. References dump(), LLRP::CErrorDetails::m_eResultCode, LLRP::CTypeDescriptor::m_pName, LLRP::CFieldDescriptor::m_pName, LLRP::CErrorDetails::m_pRefField, LLRP::CErrorDetails::m_pRefType, and LLRP::RC_OK.
