class TPtrC8 : public TDesC8;
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.

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.
|
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.
|
IMPORT_C TPtrC8(const TUint8 *aBuf, TInt aLength);
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.
|
|
inline void Set(const TUint8 *aBuf, TInt aLength);
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.
|
|
inline void Set(const TDesC8 &aDes);
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.
|
inline void Set(const TPtrC8 &aPtr);
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.
