[PATCH] doc: fix variable's type in code snippet in manual

[Guillermo E. Martinez]

  declaring int b[4] and using read (fd, &b[i], 1),
  just read the first 8-bits for an integer variable
  (32-bits wide). So doing the OR and bit shift operations
  doesn't warranty that most significat bits are zeros,
  and the computed number value is not right.
