NAME
setlogmask - set log priority mask SYNOPSIS
#include
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 calling process, and returns the previous mask. If the mask argument is 0, the current logmask is not modified. The eight priorities are LOGEMERG, LOGALERT, LOGCRIT, LOGERR, LOGWARNING, LOGNOTICE, LOGINFO, and LOGDEBUG. The bit correspond‐ ing to a priority p is LOGMASK(p). Some systems also provide a macro LOGUPTO(p) for the mask of all priorities in the above list up to and including p. RETURN VALUE This function returns the previous log priority mask. ERRORS None. CONFORMING TO POSIX.1-2001. Note that the description in POSIX.1-2001 is flawed. SEE ALSO closelog(3), openlog(3), syslog(3) COLOPHON
