RedHat 9 (Linux i386) - man page for setlogmask (redhat section 3)

SETLOGMASK(3)			    Linux Programmer's Manual			    SETLOGMASK(3)

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 syslog(3) may be logged.
       All other calls will be ignored.  Logging is enabled for the priorities that have the cor-
       responding bit set in mask.  The initial mask is such that logging is enabled for all pri-
       orities.

       The setlogmask() function sets this logmask for the current process, and returns the  pre-
       vious 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  sys-
       tems  also provide a macro LOG_UPTO(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
       XPG4.  Note that the description in POSIX 1003.1-2001 is flawed.
