setlogmask — set log priority mask
#include <syslog.h>
int
setlogmask( |
int mask); |
A process has a log priority mask that determines which
calls to syslog(3) may be logged.
All other calls will be ignored. Logging is enabled for the
priorities that have the corresponding bit set in mask. The initial mask is such
that logging is enabled for all priorities.
The setlogmask() function
sets this logmask for the calling process, and returns the
previous mask. If the mask argument is 0, the current logmask
is not modified.
The eight priorities are LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, and LOG_DEBUG. The bit corresponding to a
priority p is LOG_MASK(p). Some systems
also provide a macro LOG_UPTO(p) for the mask of
all priorities in the above list up to and including
p.
