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():
    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.  

VERSIONS

addseverity() is provided in glibc since version 2.1.
