16-bit non-modifiable pointer descriptor.
This is a descriptor class intended for instantiation and encapsulates a pointer to the 16-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 TUint16 * | iPtr | [protected] |
| IMPORT_C | TPtrC16 | ( | ) |
Constructs an empty 16-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 | TPtrC16 | ( | const TDesC16 & | aDes | ) |
Constructs the 16-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 a 16-bit non-modifiable descriptor. |
| IMPORT_C | TPtrC16 | ( | const TUint16 * | aString | ) |
Constructs the 16-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 16-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.
USER 17 if aLength is negative.
| 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. |
Sets the 16-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 | 17, if aLength is negative. |
| void | Set | ( | const TDesC16 & | aDes | ) | [inline] |
Sets the 16-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 a 16-bit non-modifiable descriptor |
