| RMemWriteStream() | |
| RMemWriteStream(const MExternalizer< TStreamRef > &) | |
| RMemWriteStream(TAny *, TInt) | |
| IMPORT_C void | Open(TAny *, TInt) |
Supports the writing of a stream to a pointer of any type.
See also: TMemBuf RWriteStream
| RMemWriteStream | ( | ) | [inline] |
Constructs an empty write stream object.
Call Open() to prepare a stream for writing.
| RMemWriteStream | ( | const MExternalizer< TStreamRef > & | anExter | ) | [inline] |
Constructs a write stream with an externalizer. For example, CStoreMap implements MExternalizer<TStreamRef>.
See also: MExternalizer CStoreMap
| Parameter | Description |
|---|---|
| anExter | Specifies an externalizer. |
Constructs the RMemWriteStream object and prepares a stream to be hosted in the specified memory location (described by the TAny aPtr argument) for writing using the Open() function.
See also: RMemWriteStream::Open
| Parameter | Description |
|---|---|
| aPtr | The start address for the area of memory that is the sink of this stream. |
| aMaxLength | The maximum length of the area of memory. |
Prepares a stream for writing.
When streaming takes place any existing data in the memory location will be replaced. Note that the length of memory must be big enough to accommodate the expected streamed data otherwise the subsequent streaming operation will leave with KErrOverFlow.
To close the stream and free its resources call Close()

| Parameter | Description |
|---|---|
| aPtr | The start address for the area of memory that is the sink of this stream. |
| aMaxLength | The maximum length of the area of memory. |
