<H3>Return Value</H3>
On success, TRUE is returned.<BR>
On failure, FALSE is returned.<BR>
<H3>Remarks</H3>
You must always unlock the data again after you have finished with it, using FSOUND_Sample_Unlock.<BR>
For PCM based samples, data must be signed 8 or 16bit. For compressed samples such as those created with FSOUND_IMAADPCM, FSOUND_VAG, FSOUND_GCADPCM, the data must be in its original compressed format.<BR>
On PlayStation 2, with FSOUND_HW2D or FSOUND_HW3D based samples, this function does not return a readable or writable buffer, it returns the SPU2 address of the sample. To send data to it you must call FSOUND_SendData.<BR>
On GameCube, with FSOUND_HW2D or FSOUND_HW3D based samples, this function will not return the data contained within the sample. It is for upload purposes only.<BR>
