MSHCTX
The MSHCTX enumeration constants specify the destination context, that is, the process
in which the unmarshaling is to be done. These flags are used in the IMarshal and IStdMarshalInfo interfaces and in the CoMarshalInterface and CoGetStandardMarshal API functions.
MSHCTX is defined in WTYPES.IDL.
typedef enum tagMSHCTX
{
MSHCTX_LOCAL = 0,
MSHCTX_NOSHAREDMEM = 1,
MSHCTX_DIFFERENTMACHINE = 2,
MSHCTX_INPROC = 3
} MSHCTX;
Elements
MSHCTX_LOCAL
The unmarshaling process is local and has shared memory access with the
marshaling process.
MSHCTX_NOSHAREDMEM
The unmarshaling process does not have shared memory access with the
marshaling process.
MSHCTX_DIFFERENTMACHINE
The unmarshaling process is on a different machine. The marshaling code cannot
assume that a particular piece of application code is installed on that
machine.
MSHCTX_INPROC
The unmarshaling will be done in another apartment in the same process. If
your object supports multiple threads, your custom marshaler can pass a direct
pointer instead of creating a proxy object.
