Static methods:

• public static void uniform_1f (int uniform_no, float value)
  Changes the value of a floating point uniform in the currently used (see use) shader program.
• public static void uniform_1i (int uniform_no, int value)
  Changes the value of an integer uniform in the currently used (see use) shader program.
• public static void uniform_float (int uniform_no, int size, float[] value)
  Changes the value of a float vector uniform, or uniform array in the currently used (see use) shader program.
• public static void uniform_int (int uniform_no, int size, int[] value)
  Changes the value of a int vector uniform, or uniform array in the currently used (see use) shader program.
• public static void uniform_matrix (int uniform_no, int size, bool transpose, float[] value)
  Changes the value of a matrix uniform, or uniform array in the currently used (see use) shader program.

Creation methods:

• public Program ()
  Create a new cogl program object that can be used to replace parts of the GL rendering pipeline with custom code.

Methods:

• public void attach_shader (Shader shader_handle)
  Attaches a shader to a program object.
• public int get_uniform_location (string uniform_name)
  Retrieve the location (offset) of a uniform variable in a shader program, a uniform is a variable that is constant for all vertices/fragments for a shader object and is possible to modify as an external parameter.
• public void link ()
  Links a program making it ready for use.
• public void use ()
  Activate a specific shader program replacing that part of the GL rendering pipeline, if passed in COGL_INVALID_HANDLE the default behavior of GL is reinstated.
