[Gnuplot-info] Plotting fifo

[Qiang J. <jiq...@in...>]

Hi all,

    I'm writing a program which solves a system of m differential 
equations in C(m is variable). In each step, I should draw m curses in 
the same graphic. To realise the real-time update of the graphic, I 
thought of use the FIFOs and plot the fifos in each step. The problem is 
that I create m FIFOs (I've tried with a fifo and m+1 columns, that 
didn't work),and the command gnuplot is:
plot "nameoffifo1" using 1:2 with linespoints,\
        "nameoffifo2" using 1:2 with linespoints,\
          ...
         "nameoffifom" using 1:2 with linespoints,\n
The program hangs when it try to write in the second fifo. I guess the 
problem is that gnuplot take just the first line in a time, it reads 
only the first fifo until the program finishes, so only the first fifo 
can work, the others, when i do a fopen, there's a dead lock.

I would like to know if anyone has a solution for this. Thank you.
