### Function

# GLib Uriunescape_string

since: 2.16

#### Declaration [src]

    char*
    g_uri_unescape_string (
      const char* escaped_string,
      const char* illegal_characters
    )

#### Description [src]

Unescapes a whole escaped string.

If any of the characters in `illegal_characters` or the NUL character appears as an escaped character in `escaped_string`, then that is an error and `NULL` will be returned. This is useful if you want to avoid for instance having a slash being expanded in an escaped path element, which might confuse pathname handling.
