<!-- ================================ PARAMETERS -->
<refsect1 id="parameters"><title>Parameters</title>
<variablelist>
<varlistentry>
<term><varname>num_entries</varname></term>
<listitem>
<para>
The number of <type>cl_platform_id</type> entries that can
be added to <varname>platforms</varname>. If <varname>platforms</varname>
is not NULL, then <varname>num_entries</varname> must be greater than zero.

<varlistentry>
<term><varname>platforms</varname></term>
<listitem>
<para>
Returns a list of OpenCL platforms available for access through the
Khronos ICD Loader. The <type>cl_platform_id</type> values returned in
<varname>platforms</varname> are ICD compatible and can be used to
identify a specific OpenCL platform. If the <varname>platforms</varname>
argument is NULL, then this argument is ignored. The number of
OpenCL platforms returned is the minimum of the value specified by
<varname>num_entries</varname> or the number of OpenCL platforms available.
</para>

<listitem>
<errorname>CL_INVALID_VALUE</errorname> if <varname>num_entries</varname>
is equal to zero and <varname>platforms</varname> is not NULL or if both
<varname>num_platforms</varname> and <varname>platforms</varname> are NULL.
