read from the stream. The number of bytes read may be less than the number requested.
- Parameters:
-
[in] dest the destination address to which the data will be read [in] count the number of bytes requested
- Returns:
- the number of bytes read from the stream.
Implements PxInputStream.
| virtual void PxDefaultFileInputData::seek | ( | PxU32 | offset | ) | [virtual] |
seek to the given offset from the start of the data.
- Parameters:
-
[in] offset the offset to seek to. If greater than the length of the data, this call is equivalent to seek(length);
Implements PxInputData.
| virtual PxU32 PxDefaultFileInputData::tell | ( | ) | const [virtual] |
return the current offset from the start of the data
- Returns:
- the offset to seek to.
Implements PxInputData.
