No values are returned.

Attaches a shader object to a program object.

Set program to a program object and shader to a shader object. You can attach three types of shaders to a single program: vertex shader objects generated by glCreateShader, geometry shader objects generated by glCreateShader, and the reserved fragment shader GL_DMP_FRAGMENT_SHADER_DMP.

To use a program object, you must at least attach a vertex shader object and the reserved fragment shader.

This function generates the following errors.

GL_INVALID_VALUE	The program argument is a nonexistent program object or shader is a nonexistent shader object.
GL_INVALID_OPERATION	The shader argument, or another shader object of the same type, is already attached to program.
