john,
thanks. the additional "fflush(a)" does not help.
hm. do you have any idea, why i don't get anything back,
when i execute the same statements in a m-file ?
regards, andreas.
octave.exe:6> [a,b,i]=popen2('python','svr_02.py')
octave.exe:7> fputs(a,"test_cmd\n")
octave.exe:8> fgets(b) # ans = got command test_cmd
octave.exe:9> fputs(a,"0\n")
octave.exe:10> fflush (a) # ans = 0
octave.exe:11> fgets (b) # ans = -1, still...
octave.exe:12> fclear(b)
octave.exe:13> fgets(b) # ans = got command 0
