oracular (3) nbd_set_debug.3.gz

Provided by: libnbd-dev_1.20.3-1_amd64 bug

NAME
       nbd_set_debug - set or clear the debug flag


SYNOPSIS
        #include <libnbd.h>

        int nbd_set_debug (
              struct nbd_handle *h, bool debug
            );


DESCRIPTION
       Set or clear the debug flag.  When debugging is enabled, debugging messages from the library are printed
       to stderr, unless a debugging callback has been defined too (see nbd_set_debug_callback(3)) in which case
       they are sent to that function.  This flag defaults to false on newly created handles, except if
       "LIBNBD_DEBUG=1" is set in the environment in which case it defaults to true.


RETURN VALUE
       If the call is successful the function returns 0.


ERRORS
       On error -1 is returned.

       Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.

       The following parameters must not be NULL: "h".  For more information see "Non-NULL parameters" in
       libnbd(3).


VERSION
       This function first appeared in libnbd 1.0.

       If you need to test if this function is available at compile time check if the following macro is
       defined:

        #define LIBNBD_HAVE_NBD_SET_DEBUG 1
