Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The setlogmask() function sets the log priority mask to maskpri and returns the previous mask. Calls to syslog() or vsyslog() with a priority that isn't set in maskpri are rejected.
You can calculate the mask for an individual priority pri with the macro:
LOG_MASK(pri);
You can get the mask for all priorities up to and including toppri with the macro:
LOG_UPTO(toppri);
The default allows all priorities to be logged. See the syslog() function for a list of the priorities.
Returns:
The previous log mask level.
Examples:
See syslog().
