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.
