ı meant that if you state volatile variable in C, you can use it on any loop as variable. it's not necassary to introduce one more times in loop which uses volatile variable. ı want to do like this for an image that ı loaded

please edit your question , and try to make your situation much more clear.

are you afraid, the compiler tries to optimize the imread call away ?

Hi,I think your problem can be solved by defining a global variable.

something like this:

void main void()
{
Mat img=imread("Nature.jpg");
for(;;) //for loop #1
{
//use img here
}

for(;;) //for loop #2
{
//use img here
}
and so on...

return 0;
}

this does not solve my problem because actually ı had to indicate that any function instead of any loop. it's my mistake... ı want to use that image all functions which are out of main()
