Question

I want to save a location in file, and later restore the file pointer to the saved location.

 FILE *save = fp;

//perform operations on file fp...  

..
..

//restore to previously saved location

fp = save;  

I tried the above method, but it does not work.

Answer 1

See this page for information about the ftell and fseek functions. These will allow you to retrieve and set the position of the file pointer, respectively.

long int originalPos = ftell(fp);
// do stuff with file
fseek(fp, originalPos, SEEK_SET);
