get_string

Returns the string value associated with key under group_name.

Unlike [method@GLib.KeyFile.get_value], this function handles escape sequences like `\s`.

If the key cannot be found, [error@GLib.KeyFileError.KEY_NOT_FOUND] is returned. If the group_name cannot be found, [ error@GLib.KeyFileError.GROUP_NOT_FOUND] is returned.

Parameters:

this	a key file
group_name	a group name
key	a key

Returns:

a newly allocated string or `NULL` if the specified key cannot be found.
