GLib.Regex.split_full

### Method

# GLib Regexsplit_full

since: 2.14

#### Declaration [src]

    gchar**
    g_regex_split_full (
      const GRegex* regex,
      const gchar* string,
      gssize string_len,
      gint start_position,
      GRegexMatchFlags match_options,
      gint max_tokens,
      GError** error
    )

#### Description [src]

Breaks the string on the pattern, and returns an array of the tokens. If the pattern contains capturing parentheses, then the text for each of the substrings will also be returned. If the pattern does not match anywhere in the string, then the whole string is returned as the first token.

As a special case, the result of splitting the empty string “” is an empty vector, not a vector containing a single string. The reason for this special case is that being able to represent an empty vector is typically more useful than consistent handling of empty elements. If you do need to represent empty elements, you’ll need to check for the empty string before calling this function.

A pattern that can match empty strings splits `string` into separate characters wherever it matches the empty string between characters. For example splitting “ab c” using as a separator “\s*”, you will get “a”, “b” and “c”.

Setting `start_position` differs from just passing over a shortened string and setting `G_REGEX_MATCH_NOTBOL` in the case of a pattern that begins with any kind of lookbehind assertion, such as “\b”.

Available since: 2.14

#### Parameters

`string`

  Type: An array of `gchar`

  The string to split with the pattern.

  The length of the array is specified in the `string_len` argument.
  The data is owned by the caller of the method.
  Each element is a NUL terminated UTF-8 string.

`string_len`

  Type: `gssize`

  The length of `string`, in bytes, or -1 if `string` is nul-terminated.

`start_position`

  Type: `gint`

  Starting index of the string to match, in bytes.

`match_options`

  Type: `GRegexMatchFlags`

  Match time option flags.

`max_tokens`

  Type: `gint`

  The maximum number of tokens to split `string` into. If this is less than 1, the string is split completely.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: An array of `utf8`

A `NULL`-terminated gchar ** array. Free it using g_strfreev().

The array is `NULL`-terminated.
The caller of the method takes ownership of the returned data, and is responsible for freeing it.
Each element is a NUL terminated UTF-8 string.
