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 nonnegative.

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.
