pipes: problem - simplified

[edek]

int test[2];
        pipe(test);
        FILE *to, *from;
        if ((to = fdopen(test[1], "w")) == NULL)
           return 1; //error: could not create stream
        if ((from = fdopen(test[0], "r")) == NULL)
           return 1; //error: could not create stream
        
        fputs("test text", to);
        
        char testBuff[5];
        fgets(testBuff, 5, from);
        
        puts(testBuff); //This should display 'test' in console - it does not, why?

The code above doesn't work - it displays nothing. I think that fgets(...) waits for input, but I used fputs(...) to send some text through pipe. How to make it work???

PS. This is just an example code - I just would like to know where do I think wrong?? Doesn't pipes work like some kind of buffers???
