Function

GLiblistenv

since: 2.8

Declaration [src]

gchar**
g_listenv (
  void
)

Description [src]

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.

Available since: 2.8

Return value

Type: An array of filename

a `NULL`-terminated list of strings which must be freed with
g_strfreev().

The array is NULL-terminated.

The caller of the function takes ownership of the data, and is responsible for freeing it.

Each element is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows..
