Word description Defines a new shader program named program-name. When the program is instantiated with <program-instance>, it will link together instances of all of the specified shader s to create the program instance. If any vertex-format s are specified, their attributes will be pre-assigned attribute indexes at link time, to ensure that their indexes remain constant if the program is refreshed with refresh-program. A transform feedback vertex format may optionally be specified with feedback-format:; if the program is used to collect transform feedback, the given vertex format will be used for the output.
Notes Transform feedback requires OpenGL 3.0 or one of the GL_EXT_transform_feedback or GL_ARB_transform_feedback extensions.
