Name

glIsQuery — determine if a name corresponds to a query object

C Specification

GLboolean glIsQuery(GLuint id);

Parameters

id

Specifies a value that may be the name of a query object.

Description

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.
