I am for some reason getting a SIGTERM signal sent from the os when running my program.

        top_io.open("type_of_pixel.txt", ios::out | ios::in);
        if (top_io.is_open() && !top_io.fail() && top_io.good()) {
            top_io.seekg(0, ios::beg);
            top_io.seekp(0, ios::beg);
            int test = 0;
            for (long a = 0; !top_io.eof(); a++) {
                top_io << test;
                if (a == Platform_del) {
                    top_io << 0;
                }
            }
            
            top_io.close();
            mouse_was_clicked = false;
        
    }
        else {
            cout << "Error";
        }

it appears the signal is coming from this line:

 top_io << test; 

I am using xcode on a mac with c++. PLease help me.
Thanks

for (long a = 0; !top_io.eof(); a++)

This loop terminates when an I/O operation causes the eofbit to be set.

What line within that loop would cause the eofbit to be set?

[jtreiner]

The file was written in another block of code. I think that should answer your question. If not please explain.

Ok, I don't think you understood what I'm asking at all.

Why did you type !top_io.eof() in that code?

[jtreiner]

I tried something else which fixed the SIGTERM signal but caused another problem:

        top_io.open("type_of_pixel.txt", ios::out | ios::in);
        if (top_io.is_open() && !top_io.fail() && top_io.good()) {
            top_io.seekg(0, ios::beg);
            top_io.seekp(0, ios::beg);
            int test = 0;
            for (long a = 0; !top_io.eof(); a++) {
                top_io << test;
                if (a == Platform_del) {
                    top_io << 0;
                    return;
                }
            }
            
            top_io.close();
            mouse_was_clicked = false;
        
    }
        else {
            cout << "Error";
        }

I added the return line but now my program says error in the console.

Why did you type !top_io.eof() in that code?

It is so the loop will end once it reaches the end of the file.

Yes, very good. Now, tell me, how do you reach the end of the file? Which line of code could cause you to hit the end of the file?

[jtreiner]

shouldn't ">>" put the next line of code into a variable and it keeps going forward until it reaches the end?

[Oler1s]

> shouldn't ">>" put the next line of code into a variable

Correct. Here's what I want you to do:

Copy paste only the line of code that has >> in it. Highlight the >> in red for us to see.

Oh hahahahaha

EVERYONE THUMBS UP older1s

BUt i am still having the same problem

Post your fixed code that should have resolved the SIGTERM issue.

        top_io.open("type_of_pixel.txt", ios::out | ios::in);
        if (top_io.is_open() && !top_io.fail() && top_io.good()) {
            top_io.seekg(0, ios::beg);
            top_io.seekp(0, ios::beg);
            int test = 0;
            for (long a = 0; !top_io.eof(); a++) {
                top_io >> test;
                if (a == Platform_del) {
                    top_io << 0;
                    return;
                }
            }
            
            top_io.close();
            mouse_was_clicked = false;
        
    }
        else {
            cout << "Error";
        }

I added the

 return; 

line and it fixed the SIGTERM problem but now I get "error" in the console.
The error is from:

        else {
            cout << "Error";
        }

Can someone please help me

[jimblumberg]

You need to show a little patience.

First why do you have so many conditions in your if statement?

   if (top_io.is_open() && !top_io.fail() && top_io.good()) {

A simple way of checking if a file opened correctly is:

   if (top_io) {

This checks if there are any error conditions.

Next, what type of stream is top_io? An ifstream, ofstream, fstream?

fstream

I don't mean to be impatient but I need to get this code fixed as soon as possible. If anyone can help me please do.
Thanks
