+// All patchable constants need to be defined in a separate file.
+// Care should be taken not to define the constant data in the same source file in which
+// they are referred, lest the compiler inline's it. If inlined, the data has no storage
+// location and cannot be patched.
+// Hence, the definition of data must be put in a separate source file and they must be 
+// referred in other source files by using the 'extern' qualifier.
+//

+//This constant lets licensees specify a list of drives which they
+//do not want ECOM to scan, e.g. because the drives can never have
+//valid plug-ins. 
+//This is a 32-bit integer with each bit representing a drive to disable:
+//0x1 disables drive A, 0x2 disables drive B etc. There are only 25 drive
+//letters supported (A:->Y:) therefore the last 7 bits are ignored.
+//Note that Read-only internal drives cannot be disabled.

+// This constant specifies the maximum number of resolver DLLs ECOM can cache.
+// When the cache queue is full, the next custom resolver DLL requested by
+// client will bump off the oldest DLL in the cache.
+// The default (unpatched) value is 4.

+// This constant specifies the timeout in microseconds that a resolver DLL is
+// kept in cache. When the time expires, the resolver DLL is released from
+// memory. The default (unpatched) value is 4000000.
