Set_Environment(4)DEVICES AND NETWORK INTERFACESet_Environment(4)
Set_Environment request - set a tool's environment
Set_Environment(in string variable,
in string value
The Set_Environment request replaces the value of the indi-
cated environment variable(s).
The variable argument is the name of the environment vari-
able to set.
The value argument is the value of the environment variable.
If this argument is unset (in other words, has a value of
(char *)0), then the variable should be removed from the
environment. It is not an error for the variable not to
have existed in the first place.
The ttdt_session_join(3), function can be used to register
for, and transparently process, the Set_Environment request.
The Set_Environment request can be sent as in the following
Tt_message msg = tttk_message_create(0, TT_REQUEST, TT_SESSION,
tt_message_arg_add(msg, TT_IN, Tttk_string, "PATH");
tt_message_arg_add(msg, TT_IN, Tttk_string, "/bin:/usr/ucb");
Set_Environment can also be sent as a multicast notice, as
an edict to all tools in the scope of the message. The
consequences of doing so can be severe and unexpected.
ttdt_session_join(3); Get_Environment request.
