See the docs, section GUI routines:
"The dialog procedure should follow the form:
   int foo(int msg, DIALOG *d, int c);

The dialog procedure should return one of the values:

   D_O_K          - normal return status
   D_CLOSE        - tells the dialog manager to close the dialog
   D_REDRAW       - tells the dialog manager to redraw the entire dialog
   D_REDRAWME     - tells the dialog manager to redraw the current object
   D_WANTFOCUS    - requests that the input focus be given to this object
   D_USED_CHAR    - MSG_CHAR and MSG_XCHAR return this if they used the key"
