This is a basic application logging facility.

It uses printf style formatting and provides several mechanisms for output.

Function Documentation

int gossip_disable (  void   )

Turns off any active logging facility and disables debugging. Returns: 0 on success, -errno on failure.

int gossip_enable_file (  const char *  filename, const char *  mode )

Turns on logging to a file. The filename argument indicates which file to use for logging messages, and the mode indicates whether the file should be truncated or appended (see fopen() man page). Returns: 0 on success, -errno on failure.

Here is the call graph for this function:

int gossip_enable_stderr (  void   )

Turns on logging to stderr. Returns: 0 on success, -errno on failure.

Here is the call graph for this function:

int gossip_enable_syslog (  int  priority  )

Turns on syslog logging facility. The priority argument is a combination of the facility and level to use, as seen in the syslog(3) man page. Returns: 0 on success, -errno on failure.

Here is the call graph for this function:

int gossip_err (  const char *  format, ...  )

Logs a critical error message. This will print regardless of the mask value and whether debugging is turned on or off, as long as some logging facility has been enabled. Returns: 0 on success, -errno on failure.

int gossip_get_debug_mask (  int *  debug_on, uint64_t *  mask )

Fills in args indicating whether debugging is on or off, and what the mask level is. Returns: 0 on success, -errno on failure.

int gossip_set_debug_mask (  int  debug_on, uint64_t  mask )

Determines whether debugging messages are turned on or off. Also specifies the mask that determines which debugging messages are printed. Returns: 0 on success, -errno on failure.
