umad_debug - set debug level

#include <infiniband/umad.h>

int umad_debug(int level);

umad_debug() sets the umad library internal debug level to level. The following debug levels are supported: 0 - no debug (the default), 1 - basic debug information, 2 - verbose debug information. Negative values are ignored in terms of set. Note that the current debug level can be queried by passing a negative value as level.

umad_debug() returns the actual debug level.
