GL_INVALID_VALUE in glUseProgram on resuming app

I am getting GL_INVALID_VALUE​, 0x0501 error at glUseProgram(mYUVProgram); in the following code. It occurs on resuming the app. According to glUseProgram docs

GL_INVALID_VALUE is generated if program is neither 0 nor a value generated by OpenGL.

I want to know how I can check the value of mYUVProgram, whether its valid or no, after the app has resumed. So that I can create the shader program again if mYUVProgram's value is invalid. (I am just beginner in OpenGL so please forgive me if this question is too trivial)

CODE

void draw() {
 if (!mFrameTexture) {
    glGenTextures( 1, &mFrameTexture );
    mProgram = Shaders::addProgram(this, (char *) Shaders::vertexShader,
                                                 (char *) Shaders::fragmentShader);
    //other initialization code
    CCLOG("draw:: added shader");
 }

  glUseProgram(mYUVProgram);
  //other drawing code
  }

Correct me if I am wrong , but I believe this is what you are looking for?

eg.

if ( glIsProgram( mYUVProgram ) != GL_TRUE ){
  // Recreate mYUVProgram
}
 glUseProgram( mYUVProgram);
