to be called. Also, this function has to be called after the interrupt occurs, because the

system part of the interrupt handling procedure masks the interrupts.

Example

/* global section */

/* define USER type to pass data to/from the user interrupt

handling function. Assume components' types are defined */

struct USER {

SOMETYPE user1;

ANOTHERTYPE user2;

YETANOTHERTYPE user3;

};

struct USER user;

INT_DATA intdata;

/* end of global section */

ECODE ecode;

HFG hfg;

BUFFER buffer;

BOOL enough;

/* Initialize the system, allocate buffer(s), get handles here

/* Set up INT_DATA */

intdata.hfg = hfg;

intdata.mask = STATUS_READY;

intdata.func = UserFunc; //see below;

intdata.priority = THREAD_PRIORITY_NORMAL;

/* Set up the necessary user data */

user.user2 = NOT_READY; //some user flag;

/* Enable interrupt */

if (!(ecode = X11_InterruptOn (&intdata))) {

if (!(ecode = X11_InterruptUnmask (hfg, STATUS_READY))) {

/* start acquisition */

X11_StartAcquire (hfg, buffer.hbuf, AMODE_SINGLE);

/* do whatever is necessary here,

for example: */

while (!enough) {

user.user2 = NOT_READY;

/* start next acquisition */

AMODE_SINGLE);

/* image is ready, do something with it*/
