DESCRIPTION

18       This function allows the introduction of new severity classes which can
19       be addressed by the severity argument of the  fmtmsg(3)  function.   By
20       default  that  latter  function  only  knows  how to print messages for
21       severity 0-4 (with strings (none), HALT, ERROR, WARNING,  INFO).   This
22       call  attaches the given string s to the given value severity.  If s is
23       NULL, the severity class with the numeric value  severity  is  removed.
24       It  is  not possible to overwrite or remove one of the default severity
25       classes.  The severity value must be nonnegative.
26

RETURN VALUE

28       Upon success, the value MM_OK is  returned.   Upon  error,  the  return
29       value  is MM_NOTOK.  Possible errors include: out of memory, attempt to
30       remove a nonexistent or default severity class.
31

VERSIONS

33       addseverity() is provided in glibc since version 2.1.

41       able SEV_LEVEL.
