The <code class="Fn">zip_set_default_password</code>() function sets the default
password used when accessing encrypted files. If
<var class="Ar">password</var> is <code class="Dv">NULL</code> or the empty
string, the default password is unset.
<p class="Pp">If you prefer a different password for single files, use
<a class="Xr" href="zip_fopen_encrypted.html">zip_fopen_encrypted(3)</a>
instead of <a class="Xr" href="zip_fopen.html">zip_fopen(3)</a>. Usually,
however, the same password is used for every file in an zip archive.</p>
<p class="Pp">The password is not verified when calling this function. See the
<a class="Sx" href="#CAVEATS">CAVEATS</a> section in
<a class="Xr" href="zip_fopen_encrypted.html">zip_fopen_encrypted(3)</a> for
more details about password handling.</p>

Upon successful completion 0 is returned. Otherwise, -1 is returned and the
error information in <var class="Ar">archive</var> is set to indicate the
error.
