NAME
       d_slider_proc - Dialog procedure implementing a slider control object.
       Allegro 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 contain 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.
