libadns1-dbg 1.5.0~rc1-1.1ubuntu1 (s390x binary) in ubuntu bionic

 adns is a resolver library for C (and C++) programs. In contrast
 with the existing interfaces, gethostbyname et al and libresolv, it
 can be used in an asynchronous, non-blocking manner, and has a
 convenient interface which doesn't require the application to handle
 any DNS data formats. Many queries can be handled simultaneously.
 .
 This package contains the debugging symbols associated with libadns1,
 for debugging adns and programs that use it.
