glIsQuery — determine if a name corresponds to a query object
GLboolean glIsQuery( | GLuint id) ; |
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.
