        <para>
            The <function>mput</function> function writes data to the output specified by the
            stream parameter <varname>fd</varname>. Data is written at the
            position at which the file pointer is currently pointing and
            advances the indicator appropriately.
        </para>
        <para>
            The <varname>type</varname> parameter is a conversion specifier which may be set to any of the
            following flag characters (with default value <literal>"l"</literal>):
        </para>
        <variablelist>
            <varlistentry>
                <term>"l", "i", "s", "ul", "ui", "us", "d", "f", "c", "uc"</term>
                <listitem>
                    <para>
                        for  writing respectively a long long, an int (long
                        int), a short, an unsigned long long int, an unsigned int (long int), an unsigned short, a double, a float, a char and an unsigned char. The bytes which are wrote are automatically swapped if necessary (by checking little-endian status) in order to produce machine independent binary files (in little-endian mode). This default swapping mode can be suppressed by adding a flag <code>swap = 0</code> in the <function>mopen</function> function.
                    </para>
                </listitem>

                <listitem>
                    <para>
                        It is also possible to write in little-endian or big-endian
                        mode  by adding a <literal>"l"</literal> or
                        <literal>"b"</literal> character at the end of a
                        <varname>type</varname> specification. For example
                        <literal>"db"</literal> will write a double in big-endian mode.
