How to return a 2D array from a function in C?

I am a Ruby programmer who has ended up developing a code generate for C. Its like asking a Limo to tow a 1960s truck. Any way.

Here is what I thought should work but doesnt work.

float[][] pixels()
{
  float x[][]= { {1,1},{2,2} };
  return x
}

void drawLine(float x[][2])
{
  //drawing the line
}

//inside main
drawLine(pixels());

I have banged my head on my desk trying to get this thing work. Please help.
