NAME

       comedi_loglevel - change Comedilib logging properties

SYNOPSIS

       #include <comedilib.h>

       int comedi_loglevel (int loglevel);

DESCRIPTION

       This  function  affects  the  output  of  debugging and error messages from Comedilib.  By
       increasing the loglevel, additional debugging information  will  be  printed.   Error  and
       debugging messages are printed to the stream stderr.

       The  default  loglevel  can be set by using the environment variable COMEDI_LOGLEVEL.  The
       default loglevel is 1.

       In order to conserve resources, some debugging information is  disabled  by  default  when
       Comedilib is compiled.

       The meaning of the loglevels is as follows:

       COMEDI_LOGLEVEL=0  Comedilib prints nothing.

       COMEDI_LOGLEVEL=1   (default)  Comedilib  prints  error  messages  when  there  is a self-
       consistency error (i.e., an internal bug.)

       COMEDI_LOGLEVEL=2  Comedilib prints an error message when an invalid parameter is passed.

       COMEDI_LOGLEVEL=3  Comedilib prints an error message whenever an error is generated in the
       Comedilib library or in the C library, when called by Comedilib.

       COMEDI_LOGLEVEL=4  Comedilib prints a lot of junk.

RETURN VALUE

       This function returns the previous loglevel.
