Replace the entire environment of processes launched from this launcher with the given ‘environ’ variable.
Typically you will build this variable by using
g_listenv() to copy
the process ‘environ’ and using the functions g_environ_setenv(),
As an alternative, you can use g_subprocess_launcher_setenv(), g_subprocess_launcher_unsetenv(), etc.
Pass an empty array to set an empty environment. Pass
NULL to inherit the
parent process’ environment. As of GLib 2.54, the parent process’ environment
will be copied when
g_subprocess_launcher_set_environ() is called.
Previously, it was copied when the subprocess was executed. This means the
copied environment may now be modified (using g_subprocess_launcher_setenv(),
etc.) before launching the subprocess.
On UNIX, all strings in this array can be arbitrary byte strings. On Windows, they should be in UTF-8.
