Parameters

• program
  • : The WebGLProgram to link.

Return value

None (undefined).

Examples

const program = gl.createProgram();

// Attach pre-existing shaders
gl.attachShader(program, vertexShader);
gl.attachShader(program, fragmentShader);

gl.linkProgram(program);

if (!gl.getProgramParameter(program, gl.LINK_STATUS)) {
  const info = gl.getProgramInfoLog(program);
  throw new Error(`Could not compile WebGL program. \n\n${info}`);
}
