libowfat0t64 binary package in Ubuntu Oracular armhf

 This library is a reimplementation of libdjb, which means that it provides
 Daniel Bernstein's interfaces (with some extensions).
 .
 It contains wrappers around memory allocation, buffered I/O, routines for
 formatting and scanning, a full DNS resolver, several socket routines,
 wrappers for socket functions, wait, and an abstraction
 around errno. It also includes wrappers for Unix signal functions and a
 layer of mmap and sendfile.
