nbd_set_debug - set or clear the debug flag
#include <libnbd.h> int nbd_set_debug (struct nbd_handle *h, bool debug);
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.
If the call is successful the function returns
-1 is returned.
Refer to "ERROR HANDLING" in libnbd(3) for how to get further details of the error.
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
nbd_create(3), nbd_set_debug_callback(3), nbd_set_handle_name(3), libnbd(3).
