SYNOPSIS
#include <fmtmsg.h>
int addseverity(int severity, const char *s);

_DEFAULT_SOURCE
glibc 2.19 and earlier:

DESCRIPTION
This function allows the introduction of new severity classes which can
be addressed by the severity argument of the fmtmsg(3) function. By de-
fault, 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
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.
