Member Function Documentation

virtual PxU32 PxDefaultMemoryInputData::getLength

(

)

const [virtual]

return the length of the input data

Returns:

size in bytes of the input data

Implements PxInputData.

virtual PxU32 PxDefaultMemoryInputData::read	(	void *	dest,
		PxU32	count
	)			[virtual]

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 PxDefaultMemoryInputData::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 PxDefaultMemoryInputData::tell

(

)

const [virtual]

return the current offset from the start of the data

Returns:

the offset to seek to.

Implements PxInputData.
