Описание (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.
Возвращаемое значение (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.
Версии (Versions)
addseverity() is provided in glibc since version 2.1.
