<!-- ================================ PARAMETERS -->
59
<refsect1 id="parameters"><title>Parameters</title>
63
<term><varname>num_entries</varname></term>
66
The number of <type>cl_platform_id</type> entries that can
67
be added to <varname>platforms</varname>. If <varname>platforms</varname>
68
is not NULL, then <varname>num_entries</varname> must be greater than zero.
74
<term><varname>platforms</varname></term>
77
Returns a list of OpenCL platforms available for access through the
78
Khronos ICD Loader. The <type>cl_platform_id</type> values returned in
79
<varname>platforms</varname> are ICD compatible and can be used to
80
identify a specific OpenCL platform. If the <varname>platforms</varname>
81
argument is NULL, then this argument is ignored. The number of
82
OpenCL platforms returned is the minimum of the value specified by
83
<varname>num_entries</varname> or the number of OpenCL platforms available.
89
<term><varname>num_platforms</varname></term>
92
Returns the number of OpenCL platforms available. If
93
<varname>num_platforms</varname> is NULL, then this argument is ignored.

<!-- ================================ ERRORS -->
111
<refsect1 id="errors"><title>Errors</title>
113
Returns <errorname>CL_SUCCESS</errorname> if the function is executed
114
successfully. Otherwise, it returns the following:
117
<itemizedlist mark="disc">
119
<errorname>CL_PLATFORM_NOT_FOUND_KHR</errorname> if zero platforms are available.
123
<errorname>CL_INVALID_VALUE</errorname> if <varname>num_entries</varname>
124
is equal to zero and <varname>platforms</varname> is not NULL or if both
125
<varname>num_platforms</varname> and <varname>platforms</varname> are NULL.
