return

return;

return (parameter);

Terminates the function. In the second case the given parameter is returned as result to the calling function, where it can be evaluated.

Parameters:

parameter - The value to be returned (variable, expression or pointer)

Speed:

Fast

Remarks:

!! A function that contains a wait loop can not return a parameter, because wait() already returns to the calling function before the final return statement is excecuted.

Example:

function my_distance_to_you() 
{
  if (me == NULL || you == NULL) { return(-1); } // negative distance indicates error
  return(vec_dist(my.x,your.x));
}
