- _m_e_s_g with argument nnnn forbids messages via _w_r_i_t_e(1) , _t_a_l_k or other
- utilities by revoking non-user write permission on the user's terminal.
- The terminal affected is determined by searching for the first terminal
- in the sequence of devices associated with standard input, standard
- output and standard error, respectively. _m_e_s_g with argument yyyy reinstates
- permission. All by itself, _m_e_s_g reports the current state without
- changing it. Processes with appropriate privileges may be able to send
- messages to the terminal independently of the current state.

- None.

- The following operands are supported in the POSIX locale:
-
- yyyy grant permission to other users to send messages to the terminal

- The following environment variables affect the execution of _mmmm_eeee_ssss_gggg:
-
- _LLLL_AAAA_NNNN_GGGG provide a default value for the internationalization variables that
- are unset or null. If _L_A_N_G is unset or null the corresponding value
- from the implementation-specific default locale will be used. If any
- of the internationalization variables contains an invalid setting,
- the utility will behave as if none of the variables had been
- defined.
-
- _LLLL_CCCC______AAAA_LLLL_LLLL
- if set to a non-empty string value, override the values of all the
- other internationalization variables.
-
- _LLLL_CCCC______CCCC_TTTT_YYYY_PPPP_EEEE
- determine the locale for the interpretation of sequences of bytes of
- text data as characters (for example, single - as opposed to multi-
- byte - characters in arguments).
