Question -
I write simple console functions and use freopen to redirect printf statements to a file. Can the output to the file be "turned off" and the printf outputs redirected back to the console window later in the code?
Answer -
Yes. Change your file pointer back to STDOUT.

Thanks but I tried various ways to ressign with no luck.
freopen("test.txt", "w", stdout);
then freopen(stdout, "w", "test.txt"); //wont compile.
   then I tried
temp = freopen("test.txt", "w", stdout);
then temp = stdout; // did not work.
Not sure how to reassign STDOUT.

Answer
Here is a sample program I have written to demonstrate how it works. Compile and run it.
Hope it helps....

#include<stdio.h>

main()
{
       FILE *fp = freopen("file.txt", "w", stdout);

       printf("Hello\n");

       fclose(fp);

       stdout = fdopen(2, "w");
       printf("OVER!!\n");
}
