NAME
addseverity - introduce new severity classes
SYNOPSIS
#include <fmtmsg.h>
int addseverity(int severity, const char *s);
Feature Test Macro Requirements for glibc (see

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