NAME
     d_slider_proc  - Dialog procedure implementing a slider control object. Al-
     legro game programming library.

SYNOPSIS
     #include <allegro.h>

     int d_slider_proc(int msg, DIALOG *d, int c);

DESCRIPTION
     A slider control object. This object holds a value in d2, in the range from
     0 to d1. It will display as a vertical slider if h is greater than or equal
     to w, otherwise it will display as a horizontal slider. The  dp  field  can
     contain  an  optional bitmap to use for the slider handle, and dp2 can con-
     tain an optional callback function, which is called each time  d2	changes.
     The callback function should have the following prototype:

	int function(void *dp3, int d2);

     The d_slider_proc object will return the value of the callback function.
