<function>glGetQueryiv</function> returns in <parameter>params</parameter> a selected parameter of the query object target
specified by <parameter>target</parameter>.

<para>
<parameter>pname</parameter> names a specific query object target parameter. When <parameter>pname</parameter> is

or zero if no query is active, will be placed in <parameter>params</parameter>.
If <parameter>pname</parameter> is <constant>GL_QUERY_COUNTER_BITS</constant>, the implementation-dependent number
of bits used to hold the result of queries for <parameter>target</parameter> is returned in <parameter>params</parameter>.
