How to create a temporary text file in C

Question

I have a text file to read. I would like to read from that file and store into a temporary file. I am not sure how to do this. How do I create a temporary file and do I use fprintf to store in that file?

Answer 1

You could use the function tmpfile() for that.

The tmpfile() function opens a unique temporary file in binary read/write (w+b) mode. The file will be automatically deleted when it is closed or the program terminates.

Example:

FILE * temp = tmpfile();
if(temp) {
    fprintf(temp, "Hello, Temp!");
}
