Huh?  Here's all of the code, exactly what's in the link I gave:
#include <dpmi.h>
#include <stdlib.h>
#include <sys/movedata.h>
typedef struct VESA_PM_INFO
{
        unsigned short setWindow            __attribute__ ((packed));
        unsigned short setDisplayStart      __attribute__ ((packed));
        unsigned short setPalette           __attribute__ ((packed));
        unsigned short IOPrivInfo           __attribute__ ((packed));
} VESA_PM_INFO;
VESA_PM_INFO *vesa_pm_info;
void *pm_bank_switcher;
int get_vesa_pm_functions()
{
        __dpmi_regs r;

        /* check that the driver is at least VBE version 2.0 */

        /* call the VESA function */
        r.x.ax = 0x4F0A;
        r.x.bx = 0;
        __dpmi_int(0x10, &r);
        if (r.h.ah) return -1;
        /* allocate space for the code stubs */
        vesa_pm_info = malloc(r.x.cx);
        /* copy the code into our address space */
        dosmemget(r.x.es*16+r.x.di, r.x.cx, vesa_pm_info);
        /* store a pointer to the bank switch routine */
        pm_bank_switcher = (void *)((char *)vesa_pm_info +
        vesa_pm_info->setWindow);

        return 0;
}
