 #ifndef __ECOMPATCHCONSTANTS_HBY__

 #define __ECOMPATCHCONSTANTS_HBY__

 // Macro ECOM_PATCHDATA_KLISTIMPLBUFFERSIZE represents the

 // value of the patchable constant KListImplBufferSize. It is used

 // to define the size of the buffer that is pre-allocated on the

 // ECOM client side to hold data returned by the

 // REComSession::ListImplementations() API. ECOM How To FAQ

 // explains how to determine the optimum value for this constant.

 // The default value of KListImplBufferSize is 2048.

 // 

 // This patchable constant was first introduced in Symbian_OS_v9.3.

 // At that time ECOM How To FAQ advised device builders to use

 // the "patchdata" command directly in any obey file to patch this

 // constant. The old scheme has been deprecated and the macro below

 // is the supported published mechanism for changing this patchable

 // constant. Please ensure that if this constant

 // is patched in another obey file, do not uncomment the macro

 // definition below. Otherwise this constant will be patched twice

 // with unpredictable result.

 //

 // To patch this constant, remove the comment characters and replace 2048

 // with the desired value.

 // #define ECOM_PATCHDATA_KLISTIMPLBUFFERSIZE 2048

 // Macro ECOM_PATCHDATA_KDISCOVERYDISABLEDDRIVELIST represents the

 // value of the patchable constant KDiscoveryDisabledDriveList.

 // 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.

 // The default value of KDiscoveryDisabledDriveList is 0, meaning all

 // drives are enabled.

 //

 // To patch this constant, remove the comment characters and replace 0

 // with the desired value.

 // #define ECOM_PATCHDATA_KDISCOVERYDISABLEDDRIVELIST 0x0

 // Macro ECOM_PATCHDATA_KCUSTOMRESOLVERCACHESIZE represents the

 // value of the patchable constant KCustomResolverCacheSize.

 // 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 value of KCustomResolverCacheSize is 4, meaning ECOM will

 // cache maximum of four resolver DLLs.

 //

 // To patch this constant, remove the comment characters and replace 4

 // with the desired value.

 // #define ECOM_PATCHDATA_KCUSTOMRESOLVERCACHESIZE 4

 // Macro ECOM_PATCHDATA_KCUSTOMRESOLVERCACHETIMEOUT represents the

 // value of the patchable constant KCustomResolverCacheTimeout.

 // 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 value of KCustomResolverCacheTimeout is 4000000.

 // That means if no client uses a cached resolver DLL, the DLL will be

 // unloaded after four seconds.

 //

 // To patch this constant, remove the comment characters and replace 4000000

 // with the desired value.

 // #define ECOM_PATCHDATA_KCUSTOMRESOLVERCACHETIMEOUT 4000000
