If anyone wants to know how to call GetTouchInfo() (or any other function) if it isn't part of their SDK, here's some simple example code showing how to do it:

#include <stdio.h>
#include <dlfcn.h>

#define EVT_MTSYNC 39
#define EVT_POINTERDRAG 44

typedef struct iv_mtinfo_s {
  int active;
  int x;
  int y;
  int pressure;
  int rsv_1;
  int rsv_2;
} iv_mtinfo;

iv_mtinfo* (*gti)(void);  /* Pointer to GetTouchInfo() function. */

int main_handler(int type, int par1, int par2) {
  void *handle;
  iv_mtinfo *mti;
  int i;

  if (type == EVT_INIT) {
    if ((handle = dlopen("libinkview.so", RTLD_LAZY))) {
      *(void **) (&gti) = dlsym(handle, "GetTouchInfo");
      dlclose(handle);
    } else
      gti = NULL;
  }
 
  if type == EVT_MTSYNC) {
    if (gti && (mti = (*gti)())) {
      for (i = 0; i < par2; i++)
        printf("   x = %d, y = %d\n", mti[i].x, mti[i].y);
    }
  }

  return 0;
}

Hopefully, this will go away when a new SDK comes out.
