Routine Description:
This routine will walk down a marshalled audit parameter array and unpack it so that its information may be passed into the event logging service.
Three parallel data structures are maintained:
StringArray - Array of Unicode string structures. This array is used primarily as temporary storage for returned string structures.
StringPointerArray - Array of pointers to Unicode string structures.
FreeWhenDone - Array of booleans describing how to dispose of each of the strings pointed to by the StringPointerArray.
Note that entries in the StringPointerArray are contiguous, but that there may be gaps in the StringArray structure. For each entry in the StringPointerArray there will be a corresponding entry in the FreeWhenDone array. If the entry for a particular string is TRUE, the storage for the string buffer will be released to the process heap.
StringArray Other strings +----------------+ | |<-----------+ +----------------+ | | | | |<-------------------+ +----------------+ | | | | | UNUSED | | +----------------+ | | | | | +----------------+ | | | |<------+ | +----------------+ | | | | | | |<-----------+ | +----------------+ | | | | | | | UNUSED | | | +----------------+ | | | | | | | | +----------------+ | | | | | |<--+ | | | | | | | | | | | +----------------+ | | | | | | | | | | | | | | | | | StringPointerArray | | .... | | | | | | | | +----------------+ | | | | +-----| | | | | | +----------------+ | | | | | |---------+ | | | +----------------+ | | +----------| | | | +----------------+ | | | |-----------------+ | +----------------+ +--------------| | +----------------+ | | +----------------+ | | +----------------+ | | ....

Routine Description:
This routine converts a GUID to a string. The GUID is one of the following:
Class Guid indicating the class of an object. Property Set Guid identifying a property set. Property Guid identifying a property.
In each case, the routine returns a text string naming the object/property set or property.
If the passed in GUID is cannot be found in the schema, the GUID will simply be converted to a text string.
Arguments:

UnicodeString - Returns the text string.

This function builds a unicode string containing parameter file replacement parameters (e.g. %%1043) separated by carriage return and tab characters suitable for display via the event viewer.
The buffer returned by this routine must be deallocated when no longer needed if FreeWhenDone is true.
NOTE: To enhance performance, each time a target source module descriptor is found, it is moved to the beginning of the source module list. This ensures frequently accessed source modules are always near the front of the list.
Similarly, target object descriptors are moved to the front of their lists when found. This further ensures high performance by quicly locating

ResultantString - Points to the unicode string header. The body of this unicode string will be set to point to the resultant output value if successful. Otherwise, the Buffer field of this parameter will be set to NULL.
FreeWhenDone - If TRUE, indicates that the body of the ResultantString must be freed to process heap when no longer needed.
