pub fn listenv() -> Vec<OsString>Expand description
Gets the names of all variables set in the environment.
Programs that want to be portable to Windows should typically use this function and g_getenv() instead of using the environ array from the C library directly. On Windows, the strings in the environ array are in system codepage encoding, while in most of the typical use cases for environment variables in GLib-using programs you want the UTF-8 encoding that this function and g_getenv() provide.
§Returns
a [`None`]-terminated list of strings which must be freed with
g_strfreev().Gets the names of all variables set in the environment.
