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

NAME         top

       addseverity - introduce new severity classes

SYNOPSIS         top

       #include <fmtmsg.h>

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

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

       addseverity():
           Since glibc 2.19:
               _DEFAULT_SOURCE
           Glibc 2.19 and earlier:
               _SVID_SOURCE

DESCRIPTION         top

       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 function knows only 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 nonnegative.

RETURN VALUE         top

       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         top

       addseverity() is provided in glibc since version 2.1.

       although the fmtmsg(3) function is.  It is available on System V
       systems.

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