установить маску приоритета журнала (set log priority mask)
Имя (Name)
setlogmask - set log priority mask
Синопсис (Synopsis)
#include <syslog.h>
int setlogmask(int mask);
Описание (Description)
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.
Возвращаемое значение (Return value)
This function returns the previous log priority mask.
Ошибки (Error)
None.
