addseverity — introduce new severity classes
|const char *s
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
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
errors include: out of memory, attempt to remove a
nonexistent or default severity class.
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.
