NAME

        setlogmask - set log priority mask

SYNOPSIS

        #include <syslog.h>
 
        int setlogmask(int mask);

DESCRIPTION

        A  process  has a log priority mask that determines which calls to sys     
        log(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  current  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 correspond‐
        ing 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.
        This function returns the previous log priority mask.

ERRORS
