<para>
|
|
<function>glGetActiveAtomicCounterBufferiv</function> retrieves information about the set of active
|
|
atomic counter buffers for a program object. <parameter>program</parameter> is the name of a program
|
|
object for which the command <citerefentry><refentrytitle>glLinkProgram</refentrytitle></citerefentry>
|
|
has been issued in the past. It is not necessary for <parameter>program</parameter> to have been linked
|
|
successfully. The link may have failed because the number of active atomic counters exceeded the limits.
|
|
</para>
|
|
<para>
|
|
<parameter>bufferIndex</parameter> specifies the index of an active atomic counter buffer and must be in
|
|
the range zero to the value of <constant>GL_ACTIVE_ATOMIC_COUNTER_BUFFERS</constant> minus one. The value
|
|
of <constant>GL_ACTIVE_ATOMIC_COUNTER_BUFFERS</constant> for <parameter>program</parameter> indicates the
|
|
number of active atomic counter buffer and can be queried with
|
|
<citerefentry><refentrytitle>glGetProgram</refentrytitle></citerefentry>.
|
|
</para>
|
|
<para>
|
|
If no error occurs, the parameter(s) specified by <parameter>pname</parameter> are returned in <parameter>params</parameter>.
|
|
If an error is generated, the contents of <parameter>params</parameter> are not modified.
|
|
</para>
|
|
<para>
|
|
If <parameter>pname</parameter> is <constant>GL_ATOMIC_COUNTER_BUFFER_BINDING</constant>, then the index of the
|
|
counter buffer binding point associated with the active atomic counter buffer <parameter>bufferIndex</parameter>
|
|
for <parameter>program</parameter> is returned.
|
|
</para>
|
|
<para>
|
|
If <parameter>pname</parameter> is <constant>GL_ATOMIC_COUNTER_BUFFER_DATA_SIZE</constant>, then the implementation-dependent
|
|
minimum total buffer object size, in basic machine units, required to hold all active atomic counters in the
|
|
atomic counter binding point identified by <parameter>bufferIndex</parameter> is returned.
|
|
</para>
|
|
<para>
|
|
If <parameter>pname</parameter> is <constant>GL_ATOMIC_COUNTER_BUFFER_ACTIVE_ATOMIC_COUNTERS</constant>, then the number of active
|
|
atomic counters for the atomic counter buffer identified by <parameter>bufferIndex</parameter> is returned.
|
|
</para>
|
|
<para>
|
|
If <parameter>pname</parameter> is <constant>GL_ATOMIC_COUNTER_BUFFER_ACTIVE_ATOMIC_COUNTER_INDICES</constant>,
|
|
then a list of the active atomic counter indices for the atomic counter buffer identified by <parameter>bufferIndex</parameter>
|
|
is returned. The number of elements that will be written into <parameter>params</parameter> is the value of
|
|
<constant>GL_ATOMIC_COUNTER_BUFFER_ACTIVE_ATOMIC_COUNTERS</constant> for <parameter>bufferIndex</parameter>.
|
|
</para>

<para>

If <parameter>pname</parameter> is <constant>GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_VERTEX_SHADER</constant>,
|
|
<constant>GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_FRAGMENT_SHADER</constant>, or
|
|
<constant>GL_ATOMIC_COUNTER_BUFFER_REFERENCED_BY_COMPUTE_SHADER</constant> then a boolean value indicating
|
|
whether the atomic counter buffer identified by <parameter>bufferIndex</parameter> is referenced by the vertex,
|
|
fragment or compute processing stages of <parameter>program</parameter>, respectively, is returned.
