.SH DESCRIPTION
|
|
This function allows the introduction of new severity classes
|
|
which can be addressed by the
|
|
.I severity
|
|
parameter of the
|
|
.BR fmtmsg (3)
|
|
function.
|
|
By default that latter function only knows how to
|
|
print messages for severity 0-4 (with strings (none), HALT,
|
|
ERROR, WARNING, INFO).
|
|
This call attaches the given string
|
|
.I s
|
|
to the given value
|
|
.IR severity .
|
|
If
|
|
.I s
|
|
is NULL, the severity class with the numeric value
|
|
.I severity
|
|
is removed.
|
|
It is not possible to overwrite or remove one of the default
|
|
severity classes.
|
|
The severity value must be non-negative.
|
|
.SH "RETURN VALUE"
|
|
Upon success, the value
|
|
.B MM_OK
|
|
is returned.
|
|
Upon error, the return value is
|
|
.BR MM_NOTOK .
|
|
Possible errors include: out of memory, attempt to remove a
|
|
nonexistent or default severity class.
|
|
.SH "CONFORMING TO"
|
|

|
|
although the
|
|
.BR fmtmsg (3)
|
|
function is.
|
|
It is available on System V
|
|
systems.
|
