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



NAME
       addseverity - introduce new severity classes

SYNOPSIS
       #include <fmtmsg.h>

       int addseverity(int severity, const char *s);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       addseverity(): _SVID_SOURCE

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

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

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

CONFORMING TO
       This function is not specified in the X/Open Portability Guide although  the  fmtmsg(3)  function  is.   It  is
       available on System V systems.

NOTES
       New severity classes can also be added by setting the environment variable SEV_LEVEL.
