This class defines a interface to communicate with the legacy mbufmanager or with the system wide shared buffer mechanism
Member Functions Documentation
Alloc(TInt, TInt, TInt)
Parameters
| TInt aSize | - Requested total size |
| TInt aMinBufSize | - The size that the allocated buffer must atleast have |
| TInt aMaxBufSize | - The size that the allocated buffer "can" have. |
BytesAvailable()
|
TInt
| BytesAvailable | ( | ) | const [pure virtual] |
Total bytes available in the mbufmgr or shared buffer system
BytesAvailable(TInt)
|
TInt
| BytesAvailable | ( | TInt | aSize | ) | const [pure virtual] |
Total bytes available in a pool with a given size.
CancelRequest(CCommsBufAsyncRequest &)
Cance the request to allocate a RCommsBuf asynchronously
LargestBufSize()
|
TInt
| LargestBufSize | ( | ) | const [pure virtual] |
Larget buffer size available in the mbufmgr or shared buffer system
NextBufSize(TInt)
|
TInt
| NextBufSize | ( | TInt | aSize | ) | const [pure virtual] |
Returns the buffer size that is greater than the given size.
Release(RLibrary &)
| void | Release | ( | RLibrary & | aLib | ) | [pure virtual] |
SetContext()
| void | SetContext | ( | ) | [pure virtual] |
Set the conext. In the case of system shared buffer manager this function is not having any implmentation as the context will be set by the RCommsBufPond. For mbufmgr which is another DLL needs to set the context for the usage of global timers etc...
StartRequest(CCommsBufAsyncRequest &)
Request to allocate a RCommsBuf asynchronously
Store(TDes8 &)
|
TInt
| Store | ( | TDes8 & | aStore | ) | const [pure virtual] |
