2010 Khronos Group glIsVertexArray 3G glIsVertexArray determine if a name corresponds to a vertex array object GLboolean glIsVertexArray GLuint array array Specifies a value that may be the name of a vertex array object. glIsVertexArray returns GL_TRUE if array is currently the name of a renderbuffer object. If renderbuffer is zero, or if array is not the name of a renderbuffer 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 Khronos Group.
