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.
