- Published to all clients. Released API.
Member Function Documentation
◆ Close()
| IMPORT_C void RRawDisk::Close | ( | ) |
Closes the direct access channel to the disk, and allows other resources to access the disk.
(generated from Symbian Developer Library)
◆ Open()
| IMPORT_C TInt RRawDisk::Open | ( | RFs & | aFs, |
| TInt | aDrive | ||
| ) |
Opens a direct access channel to the disk.
Other resources are disabled from accessing the disk until Close() is called.
Note that if any resources are currently open on the disk, an error is returned.
- Parameters
-
aFs The file server session. aDrive The drive containing the disk to be accessed. Specify a drive in the range EDriveA to EDriveZ for drives A to Z.
- capability
- TCB

◆ Read()
| IMPORT_C TInt RRawDisk::Read | ( | TInt64 | aPos, |
| TDes8 & | aDes | ||
| ) |
Reads directly from the disk.
The function reads a number of bytes into the specified descriptor from the disk, beginning at the specified position.
- Parameters
-
aPos The position on the disk at which to begin reading. aDes The descriptor into which data is to be read. On return aDes contains the data read.
Panic condition: User In debug builds, the media driver panics if aPos is larger than the size of the physical media or if the end address, given by aPos + the maximum length of the descriptor, is greater than the size of the physical media.

◆ Write()
| IMPORT_C TInt RRawDisk::Write | ( | TInt64 | aPos, |
| TDesC8 & | aDes | ||
| ) |
Writes directly to the disk.
The function writes the contents of the specified descriptor to the disk at position aPos.
- Parameters
-
aPos The position at which to begin writing. aDes The descriptor containing the data to be written to the disk.
Panic condition: User In debug builds, the media driver panics if aPos is larger than the size of the physical media or if the end address, given by aPos + the maximum length of the descriptor, is greater than the size of the physical media.
