Modes

Modes for the lcb_cntl() mode argument

 Modify a setting.
 
#define LCB_CNTL_GET

Logging

Verbose logging may be enabled by default using the environment variable LCB_LOGLEVEL and setting it to a number > 1; higher values produce more verbose output.

The maximum level is 5.

You may also install your own logger using lcb_cntl() and the LCB_CNTL_LOGGER constant. Note that the logger functions will not be called rapidly from within hot paths.
