EXT_disjoint_timer_query.getQueryEXT()

The EXT_disjoint_timer_query.getQueryEXT() method of the WebGL API returns information about a query target.

any ext.getQueryEXT(target, pname);

target

A GLenum specifying the target of the time query. Must be ext.TIMESTAMP_EXT or ext.TIME_ELAPSED_EXT.

pname

A GLenum specifying which information to return. Must be ext.CURRENT_QUERY_EXT or ext.QUERY_COUNTER_BITS_EXT.

Depends on pname:

• If pname is ext.CURRENT_QUERY_EXT: A WebGLTimerQueryEXT object, which is the currently active query for the given target.
• If pname is ext.QUERY_COUNTER_BITS_EXT: A GLint indicating the number of bits used to hold the query result for the given target.

var ext = gl.getExtension('EXT_disjoint_timer_query');
var startQuery = ext.createQueryEXT();
ext.queryCounterEXT(startQuery, ext.TIMESTAMP_EXT);

var currentQuery = ext.getQueryEXT(ext.TIMESTAMP_EXT,
                                   ext.CURRENT_QUERY_EXT);
