OK. See how write and read works. > $strace echo -n "abcd" > /dev/memory(/home/aravind/me > write(1, "abcd", 4) = 1 > write(1, "bcd", 3) = 1 > write(1, "cd", 2) = 1 > write(1, "d", 1) = 1 >$ strace cat /dev/memory(/home/aravind/memory) > read(3, "d", 32768) = 1 > write(1, "d", 1d) = 1 Please allocate space for more than 1 char, and also correct memory_write tmp=buf+count-1; -> tmp=buf+*f_ps-1; thanks, Daniel. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
