ADDSEVERITY(3) Linux Programmer's Manual ADDSEVERITY(3)NAMEaddseverity - 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():
Since glibc 2.19:
_DEFAULT_SOURCE
Glibc 2.19 and earlier:
_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 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.
VERSIONSaddseverity() is provided in glibc since version 2.1.
