Collection of utility methods to work with blocking and non-blocking I/O that wrap raw POSIX
system calls, e.g. {@link android.system.Os}. These wrappers are to signal other blocked I/O
threads and avoid boilerplate code of routine error checks when using raw system calls.
<p>
For example, when using {@link Os#read(FileDescriptor, byte[], int, int)}, return value can
contain:
<ul>
<li>{@code 0} which means EOF</li>
<li>{@code N > 0} which means number of bytes read</li>
<li>{@code -1} which means error, and {@link ErrnoException} is thrown</li>
</ul>
<p>
{@link ErrnoException} in its turn can be one of:
<ul>
<li>{@link android.system.OsConstants#EAGAIN} which means the file descriptor refers to a file
or a socket, which has been marked nonblocking
({@link android.system.OsConstants#O_NONBLOCK}), and the read would block</li>
<li>{@link android.system.OsConstants#EBADF} which means the file descriptor is not a valid
file descriptor or is not open for reading</li>
<li>{@link android.system.OsConstants#EFAULT} which means given buffer is outside accessible
address space</li>
<li>{@link android.system.OsConstants#EINTR} which means the call was interrupted by a signal
before any data was read</li>
<li>{@link android.system.OsConstants#EINVAL} which means the file descriptor is attached to
an object which is unsuitable for reading; or the file was opened with the
{@link android.system.OsConstants#O_DIRECT} flag, and either the address specified in
{@code buffer}, the value specified in {@code count}, or the file {@code offset} is not
suitably aligned</li>
<li>{@link android.system.OsConstants#EIO} which means I/O error happened</li>
<li>{@link android.system.OsConstants#EISDIR} which means the file descriptor refers to a
directory</li>
</ul>
All these errors require handling, and this class contains some wrapper methods that handle most
common cases, making usage of system calls more user friendly.
