WinDbg: Regarding output of dt command

When I dump the details of a local variable using the dt command in WinDbg i get the following output:

0:000> dt uid_out
Local var @ 0x84ebbac Type CString*
0x084ebbfc 
   +0x000 m_pchData        : 0x082f2988  -> 0x31

My query is what does -> 0x31 in the final line specify? Does it specifies the size of the CString?

Thanks in advance!

This is the value of the first element of the array pointed to by a pointer type. Since m_pchData is a pointer to CHAR, the debugger shows you the first CHAR value at address 0x82f2988.

It's not being that smart, I suspect it's just the first byte of the pointer contents. You can confirm with:

dc 0x082f2988
