#include <syslog.h>
int setlogmask( int maskpri );
- maskpri
- The new log priority mask; see below.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
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.
The previous log mask level.
See syslog().
