addseverity - introduce new severity classes

int addseverity(int severity, const char *s);
This function allows the introduction of new severity classes which can be
addressed by the
severity parameter of the
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
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.
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.
New severity classes can also be added by setting the environment varible
SEV_LEVEL.
This function is not specified in the X/Open Portability Guide although the
`fmtsmg' function is. It is available on System V systems.
