<function>glGetSynciv</function> retrieves properties of a sync object. <parameter>sync</parameter> specifies the name of the sync
|
|
object whose properties to retrieve.
|

</para>
|
|
<para>
|
|
On success, <function>glGetSynciv</function> replaces up to <parameter>bufSize</parameter> integers in <parameter>values</parameter> with the
|
|
corresponding property values of the object being queried. The actual number of integers replaced is returned in the variable whose address is
|
|
specified in <parameter>length</parameter>. If <parameter>length</parameter> is <code>NULL</code>, no length is returned.

<para>

If <parameter>pname</parameter> is <constant>GL_OBJECT_TYPE</constant>, a single value representing the specific type of the sync object is

<para>

If <parameter>pname</parameter> is <constant>GL_SYNC_STATUS</constant>, a single value representing the status of the sync object

</para>

<para>

If <parameter>pname</parameter> is <constant>GL_SYNC_CONDITION</constant>, a single value representing the condition of the sync object

</para>
|

<para>
|
|
If <parameter>pname</parameter> is <constant>GL_SYNC_FLAGS</constant>, a single value representing the flags with which the sync object

was created is placed in <parameter>values</parameter>. No flags are currently supported<footnote><para><parameter>flags</parameter> is
|
|
expected to be used in future extensions to the sync objects.</para></footnote>.
