2005 Sams Publishing glIsBuffer 3G glIsBuffer determine if a name corresponds to a buffer object GLboolean glIsBuffer GLuint buffer buffer Specifies a value that may be the name of a buffer object. glIsBuffer returns GL_TRUE if buffer is currently the name of a buffer object. If buffer is zero, or is a non-zero value that is not currently the name of a buffer object, or if an error occurs, glIsBuffer returns GL_FALSE. A name returned by glGenBuffers, but not yet associated with a buffer object by calling glBindBuffer, is not the name of a buffer object. glIsBuffer is available only if the GL version is 1.5 or greater. GL_INVALID_OPERATION is generated if glIsBuffer is executed between the execution of glBegin and the corresponding execution of glEnd. glBindBuffer, glDeleteBuffers, glGenBuffers, glGet Copyright 2005 Addison-Wesley.
