<refsect1><title>Description</title>
<para>All these functions allocates necessary memory using
<function>cds_malloc</function>.</para>

<para><function>str_dup</function> takes as source the string given in
<parameter>src</parameter></para>

<para><function>str_dup_zt</function> takes as source zero-terminated string given in
<parameter>src</parameter></para>

<para><function>str_dup_new</function> works like <function>str_dup</function>
with the difference, that it allocates not only the data buffer, but the 
destination <structname>str_t</structname> structure too.
</para>

<refsect1><title>Return value</title>
<para>All these functions return 0 if successful, nonzero otherwise.
