Description Ernest Bruce 2019-01-16 02:50:09 UTC
the last sentence of the first paragraph of 4.2.1. SysV IPC says:

  The difference between a message and a signal is that the
  message only consists of the signal number.

i think the corrected sentence could read:

  The difference between a message and a signal is that
  a message contains a message id and a message pointer,
  whereas a signal contains only a signal id.
