25 This function allows the introduction of new severity classes which can
26 be addressed by the severity argument of the fmtmsg(3) function. By
27 default, that function knows only how to print messages for severity
28 0-4 (with strings (none), HALT, ERROR, WARNING, INFO). This call at‐
29 taches the given string s to the given value severity. If s is NULL,
30 the severity class with the numeric value severity is removed. It is
31 not possible to overwrite or remove one of the default severity
32 classes. The severity value must be nonnegative.
33
35 Upon success, the value MM_OK is returned. Upon error, the return
36 value is MM_NOTOK. Possible errors include: out of memory, attempt to
37 remove a nonexistent or default severity class.
