Re: character device driver reading only last character of buffer

[Bond <jamesbond.2k.g@xxxxxxxxx>]

running an strace on the program gave me

mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f2a2f03b000

write(1, "abcde", 5)                    = 1

write(1, "bcde", 4)                     = 1

write(1, "cde", 3)                      = 1

write(1, "de", 2)                       = 1

write(1, "e", 1)                        = 1

close(1)                                = 0

munmap(0x7f2a2f03b000, 4096)            = 0

close(2)                                = 0

exit_group(0)                           = ?

any suggestions here on the list are not working and people are giving me lectures.

You people show me some real code rather than speaking non sense.
