glIsQuery: determine if a name corresponds to a query object

Function Definition

 GLboolean glIsQuery(GLuint id​);
Specifies a value that may be the name of a query object.


glIsQuery returns GL_TRUE if id​ is currently the name of a query object. If id​ is zero, or is a non-zero value that is not currently the name of a query object, or if an error occurs, glIsQuery returns GL_FALSE.

A name returned by glGenQueries, but not yet associated with a query object by calling glBeginQuery, is not the name of a query object.
