Routine Description:
This routine iterates through the file system statistics structure
and accumulates a total amount for a given statistic field.
Note: This function assumes that the width of the field being accumulated
is a ULONG. If this assumption is invalidated then a width argument
should be added to this function.
Arguments:
FsStats - Pointer to an array of file system statistics structures
FsSize - Size of the individual file system statistics structures in the array
Offset - Offset of the desired field from the beginning of the file system statistics structure
NumProcs - Number of processors on the machine where the stats were gathered
Return Value:
Accumulated total.
