If array 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. glGenVertexArrays, glBindVertexArray, glDeleteVertexArrays Copyright 2010-2013 Khronos Group.
