8-bit non-modifiable pointer descriptor.
This is a descriptor class intended for instantiation and encapsulates a pointer to the 8-bit data that it represents. The data can live in ROM or RAM and this location is separate from the descriptor object itself.
The data is intended to be accessed, but not changed, through this descriptor. The base class provides the functions through which data is accessed.
| const TUint8 * | iPtr | [protected] |
| IMPORT_C | TPtrC8 | ( | ) |
Default constructor.
Constructs an empty 8-bit non-modifiable pointer descriptor.
It represents no data and its length is zero.
The non-modifiable pointer descriptor can, subsequently, be set to represent data.

| IMPORT_C | TPtrC8 | ( | const TDesC8 & | aDes | ) |
Constructs the 8-bit non-modifiable pointer descriptor from any existing descriptor.
It is set to point to the same data and is given the same length as the source descriptor.
| Parameters | |
|---|---|
| aDes | A reference to an 8bit non-modifiable descriptor. |
| IMPORT_C | TPtrC8 | ( | const TUint8 * | aString | ) |
Constructs the 8-bit non-modifiable pointer descriptor to point to a zero terminated string, whether in RAM or ROM.
The length of the descriptor is set to the length of the zero terminated string, excluding the zero terminator.
| Parameters | |
|---|---|
| aString | A pointer to a zero terminated string. |
Constructs the 8-bit non-modifiable pointer descriptor to point to the specified location in memory, whether in RAM or ROM.
The length of the descriptor is set to the specified length.
| Parameters | |
|---|---|
| aBuf | A pointer to the location that the descriptor is to represent. |
| aLength | The length of the descriptor. This value must be non-negative. |
| Panic Codes | |
|---|---|
| USER | 29 if aLength is negative. |
Sets the 8-bit non-modifiable pointer descriptor to point to the specified location in memory, whether in RAM or ROM.
The length of the descriptor is set to the specified length.
| Parameters | |
|---|---|
| aBuf | A pointer to the location that the descriptor is to represent. |
| aLength | The length of the descriptor. This value must be non-negative. |
| Panic Codes | |
|---|---|
| USER | 29, if aLength is negative. |
| void | Set | ( | const TDesC8 & | aDes | ) | [inline] |
Sets the 8-bit non-modifiable pointer descriptor from the specified descriptor.
It is set to point to the same data and is given the same length.
| Parameters | |
|---|---|
| aDes | A reference to an 8-bit non-modifiable descriptor. |
| void | Set | ( | const TPtrC8 & | aPtr | ) | [inline] |
Sets the 8-bit non-modifiable pointer descriptor from the specified non-modifiable pointer descriptor.
It is set to point to the same data and is given the same length.
| Parameters | |
|---|---|
| aPtr | A reference to an 8-bit non-modifiable pointer descriptor. |
