Here’s an example that prints a line on a different tty:

#include <stdio.h>
#include <stdlib.h>

int
main( int argc, char ** argv )
{
    char *path = argc > 1 ? argv[ 1 ] : "/dev/ttys017";
    FILE *tty = fopen( path, "a" );
    if( tty == NULL ) {
        perror( path );
        exit( EXIT_FAILURE );
    }
    fputs( "a string\n", tty );
}

Each thread could open a FILE * on a terminal specified on
the command line. If you want to create the terminals, you
can check the documentation for openpty, etc. To get the
name of a particular terminal, just run “tty” in a shell on
that terminal.
