Routine Description:
This function is called as an NTSD extension to format and dump an object attributes structure.
Arguments:
hCurrentProcess - Supplies a handle to the current process (at the time the extension was called).
hCurrentThread - Supplies a handle to the current thread (at the time the extension was called).
CurrentPc - Supplies the current pc at the time the extension is called.
lpExtensionApis - Supplies the address of the functions callable by this extension.
lpArgumentString - Supplies the asciiz string that describes the ansi string to be dumped.
Return Value:
None.

Description: This function takes the WAM_EXEC_BASE object and prints out the details for the same in the debugger. The granularity of the deatils are controlled by the verbosity flag
Arguments: pwxinOriginal - pointer to the location where the original WAM_EXEC_BASE object is located. Note: pwxinOriginal points to object inside debuggee process pwxin - pointer to the WAM_EXEC_BASE object that is a copy of the contents located at [pwxinOriginal] Note: pwxin points to object inside the debugger process Verbostiy - level of details requested.
