is zero, or if array
is not the name of a vertex array object, or if an error
occurs, glIsVertexArray
returns GL_FALSE
. If array
is a name returned by
glGenVertexArrays, by that has not yet been bound through a call to
glBindVertexArray, then the name is not a vertex array object and
glIsVertexArray
returns GL_FALSE
