2b8c2f8087 comedi_open has file descriptor leak 
If something fails after a succesful open, cleanup fails to close the file.

The code

   cleanup:
         if(it)
                 free(it);

needs to be replaced with something like:

   cleanup:
         if (it) {
           if (it->fd >= 0) {
             close(it->fd);
           }
         free(it);

Regards

b8a4f1a265 Added channel parameter to comedi_set_clock_source() and 
comedi_get_clock_source().  Bumped library version to 0.10.0.

76a2e658b7 Put __comedi_errno variable into thread-local storage if the compiler 
supports it.  Configuration test uses Alan Woodland's 'ax_tls.m4' from
<http://autoconf-archive.cryp.to/ax_tls.html>.

564e9680b0 Fixed do_test_for_insn_bits(), broken by validity checks added to 
comedi_do_insnlist().  Call comedi_ioctl() instead of comedi_do_insnlist().
 2008-12-18 17:23:14 +00:00

9a06deb6f9 Removed unneeded comedi_insnlist from do_test_for_insn(). 2008-12-18 16:44:20 +00:00
Ian Abbott
d8c3b29ca4 Corrected the 'BUG' message in do_test_for_insnlist() (it reported the 
wrong function).

4df5ffd451 Added some device and subdevice validity checks. 2008-11-05 12:52:25 +00:00
Frank Mori Hess
8103c5334a Updated it to only run the (unreliable) do_test_for_insn_bits() if the 
information was not available in the subdevice info.

e0b0b89338 Allow comedi_cleanup_calibration to accept a NULL argument. 2008-03-14 17:52:20 +00:00
Frank Mori Hess
0695475797 Updated comedi_dio_config implementation to reflect logical split 
between COMEDI_INPUT/COMEDI_OUTPUT and corresponding config insn ids
(even though they still have the same value).  Made comedi_dio_config
return 0 on success for better consistency in API.

0c69850ffc Made comedi_ioctl take its third argument as a void* instead of 
and integer type, and got rid of a bunch of casts (and added a few).

a61ed59402 Fixed return values from comedi_mark_buffer_read/written(). Removed

a06bba542a Added more INSN_CONFIG wrappers: comedi_get_clock_source(), 
comedi_get_gate_source(), and comedi_get_routing().  Added "channel"
parameter to some of the INSN_CONFIG wrappers.
 2008-01-23 18:56:52 +00:00

76791bfeed Added comedi_set_filter() and comedi_set_routing() configuration 
instruction wrappers.

and get_rangeinfo().

37dc388297 Return 0 from the INSN_CONFIG wrappers on success. 2008-01-16 20:09:38 +00:00
Frank Mori Hess
ebe72a2b2a Added more memory initialization for the sake of valgrind (especially 
memory that gets set by ioctls that valgrind can't see).  Added a little
error handling for a few memory allocations.
 2008-01-16 19:45:05 +00:00
Frank Mori Hess
4d07ce9969 Moved some wrappers for INSN_CONFIG instructions into comedilib. 
Will add some reference documentation for the new functions soon.

c1082cee65 Fixed comedi_get_cmd_generic_timed() by adding a chanlist_len 
parameter.  Old version is still available in library, thanks to the
magic of the version_script.

2b04263bed Actually, according to current:revision:age practice, the next 
release should be 0.8.0 since new functions have been added since
0.7.22.

34b9800e40 Added const qualifiers to some char* return values. Added new 
experimental comedi_dio_bitfield2() function which works with
> 32 channels.  Only works properly with ni_65xx currently.
Will post a request for review by any interested
parties to list before I bother making the rest of the drivers
work with it.
