Can't open / dev / console

//  console     = fopen("con",  "wt");       this worked under windows
//  console     = fopen("/dev/console",  "wt");     segmentation fault
    console     = fopen("/dev/tty0",  "wt");     returns zero

Writing to C using Mint Linux. I want to talk to the console regardless of the stdin and stdout redirection.

The device is /dev/consolenot necessarily available to you. For Linux, this device will only show the result if you look at the current virtual terminal. Also (including Linux) most systems /dev/consolerequire elevated permissions to open it, for example, your application works like root. The reason for this is that some system messages are written to the system console.
