Question Its a math problem isnt it?

I must have been sleeping in word problem class. Problem: I am trying to move a sprite to the mouse click coordinates with SDL.

Every iteration I use this function (if game mode is hero moving)

draw_sprites(gr, player, pdirection, ???, ??? ); //<----

void draw_sprites(GameRes *gr, Actor *a, int direction, int movex, int movey) {
  //GameRes*gr is a pointer to struct holding lots of game resources
  //int direction is only being used for which frame(s) our sprite should be displaying
  //Actor *a points to the player sprite, only x/y relevant

  gr->rcSprite->x += movex; //<-----
  gr->rcSprite->y += movey;
  //A lot of sprite frame code below
Now every time I click the mouse I get a x and y from the mouse click, lets just say mousecx, and mousecy I also have and x and y from the player sprites rectangle(rcSprite->x and rcSprite->y) Now, how do I move my rect to the mouse click coordinates? I need it to move incrementally every iteration until it reaches its destination. Maybe its Geometry? CPCTE???

I put my code up on my site
