* Makes extra sure strings are not overrun.Gravatar Erik Hovland 2008-10-281-13/+19
| | | | | | | | | When using strncpy with the exact size of the destination string the string may end up lacking null termination because the source string is bigger then the destination. Signed-off-by: Erik Hovland <erik@hovland.org> Signed-off-by: Dan Dennedy <dan@dennedy.org>
* Makes sure a value is returned by the function.Gravatar Erik Hovland 2008-10-281-0/+1
| | | | | | | A function can compile without returning something always. Signed-off-by: Erik Hovland <erik@hovland.org> Signed-off-by: Dan Dennedy <dan@dennedy.org>
* Make sure that we have the right types.Gravatar Erik Hovland 2008-10-282-7/+8
| | | | | | | | When an unsigned type is assigned a signed value, the negatived value is never seen. Signed-off-by: Erik Hovland <erik@hovland.org> Signed-off-by: Dan Dennedy <dan@dennedy.org>
* Compare unsigned values instead of subtracting them.Gravatar Erik Hovland 2008-10-281-2/+3
| | | | | | | Unsigned values do not return signed values when subtracted and the right operand is larger then the left operand. Signed-off-by: Dan Dennedy <dan@dennedy.org>

* Fix raw1394_read_cycle_timer after juju integrationGravatar Stefan Richter 2008-07-054-1/+33
| | | | | | | | The ieee1394 version of raw1394_read_cycle_timer() fell over the cliff in "First cut at integrating juju". This brings it back and adds a juju version of it. Also correct a typo in the inline documentation: s/get/read/
* Plug dir leak and initialize data structsGravatar Philippe Troin 2008-07-052-1/+16
| | | | | | | | | | | | | | While trying to track down some crashes in kino, I found the following problems with libraw1394: * There is a DIR* leak in raw1394_set_port(). * Lots of data structures are not fully initialized when calling IEEE1394 ioctl()s. These cause valgrind errors (benign, as valgrind does not know how to interpret all ioctls. However these also cause kino to crash in libraw1394. I've added a bunch of memset()s to prevent this problem from happening. Forward-ported to libraw1394 git tree by Jarod Wilson.

* eventloop.c: apply patch from Jonas Bonn to retry read when failed with EINTR.Gravatar Dan Dennedy 2008-03-271-2/+3

* Added a new callback response for iso_xmit handlers: RAW1394_ISO_AGAIN.Gravatar ddennedy 2006-03-042-0/+13
| | | | | | | | | | | | | | | This would be returned when the callback doesn't have enough data to create a complete packet. This can occur when the xmit buffers are bigger than the buffers supplying the data. It is not nescessarily an error, because there are enough packets in the xmit buffer. This response could give the data supplyer more time to fill the intermediate buffer without losing any packets.
