ADDSEVERITY(3) Linux Programmer's Manual ADDSEVERITY(3)
addseverity - introduce new severity classes
#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
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.
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.
addseverity() is provided in glibc since version 2.1.
For an explanation of the terms used in this section, see
attributes(7).

This function is not specified in the X/Open Portability Guide
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.
