cam interface support

Postby oleg2000 » Tue Apr 27, 2004 6:14 pm

Hi,
Few questions:
1. where I can get documentation about CAM interface support in QNX.
2. <sys/cpt.h> says
cam_data_ptr /*physical address of buffer or offset from start of
struct to scatter gather list */

Does it mean that I can allocate my own buffer ( with mmap) and this buffer
will be used to perform DMA ?

3. source code of ported cdrecord

regards,
Oleg
