## Subprograms

    function Convert_Error_Domain  return GQuark;

| Return the error domain associated with Glib.Convert.

    procedure Convert
      (Str                :        String;
       To_Codeset         :        String;
       From_Codeset       :        String;
       Bytes_Read         : out    Natural;
       Bytes_Written      : out    Natural;
       Error              :        GError_Access := null;
       Result             : out    String);

Convert a string from one character set to another.

Str: String to convert Result: String converted, if no error. To_Codeset: Name of character set into which to convert Str From_Codeset: Character set of Str. Bytes_Read: Number of bytes in the input string that were successfully converted. Even if the conversion was successful, this may be less than Len if there were partial characters at the end of the input. If the error Illegal_Sequence occurs, the value stored will the byte offset after the last valid input sequence. Bytes_Written: Number of bytes stored in the output buffer. Error: Location to store the error occuring, ignored if null. Any of the errors in Convert_Error_Domain may occur.

    function Convert
      (Str                :        String;
       To_Codeset         :        String;
       From_Codeset       :        String;
       Error              :        GError_Access := null)
       return String;

| Same as above, but return a String directly.

    procedure Convert
      (Str                :        chars_ptr;
       Len                :        Natural;
       To_Codeset         :        String;
       From_Codeset       :        String;
       Bytes_Read         : out    Natural;
       Bytes_Written      : out    Natural;
       Error              :        GError_Access := null;
       Result             : out    String);

| Same as Convert procedure, but take a C string as input.

    function Convert
      (Str                :        String;
       To_Codeset         :        String;
       From_Codeset       :        String;
       Bytes_Read         : access Natural;
       Bytes_Written      : access Natural;
       Error              :        GError_Access := null)
       return chars_ptr;

| Same as Convert procedure, but return the result as a C string.

    function Convert
      (Str                :        chars_ptr;
       Len                :        Natural;
       To_Codeset         :        String;
       From_Codeset       :        String;
       Bytes_Read         : access Natural;
       Bytes_Written      : access Natural;
       Error              :        GError_Access := null)
       return chars_ptr;

| Same as Convert procedure, but take and return the result as a C string.

    procedure Locale_To_UTF8
      (OS_String          :        String;
       Bytes_Read         : out    Natural;
       Bytes_Written      : out    Natural;
       Error              :        GError_Access := null;
       Result             : out    String);

Convert a string which is in the encoding used for strings by
the C runtime (usually the same as that used by the operating system) in the current locale into a UTF-8 string.

OS_String: A string in the encoding of the current locale Bytes_Read: Number of bytes in the input string that were successfully converted. Even if the conversion was successful, this may be less than Len if there were partial characters at the end of the input. If the error Illegal_Sequence occurs, the value stored will the byte offset after the last valid input sequence. Bytes_Written: Number of bytes stored in Result. Error: Location to store the error occuring, ignored if null. Any of the errors in Convert_Error_Domain may occur.

    function Locale_To_UTF8
      (OS_String          :        String;
       Bytes_Read         : access Natural;
       Bytes_Written      : access Natural;
       Error              :        GError_Access := null)
       return chars_ptr;

| Same as procedure Locale_To_UTF8, but return the raw C string for efficiency. The caller is responsible for freeing the resulting string.

    function Locale_To_UTF8
      (OS_String          :        String)
       return String;

| Same as procedure Locale_To_UTF8, but return only the String.

    procedure Locale_From_UTF8
      (UTF8_String        :        String;
       Bytes_Read         : out    Natural;
       Bytes_Written      : out    Natural;
       Error              :        GError_Access := null;
       Result             : out    String);

Convert a string from UTF-8 to the encoding used for strings by
the C runtime (usually the same as that used by the operating system) in the current locale.

UTF8_String: A UTF-8 encoded string Bytes_Read: Number of bytes in the input string that were successfully converted. Even if the conversion was successful, this may be less than Len if there were partial characters at the end of the input. If the error Illegal_Sequence occurs, the value stored will the byte offset after the last valid input sequence. Bytes_Written: Number of bytes stored in the output buffer. Error: Location to store the error occuring, ignored if null. Any of the errors in Convert_Error_Domain may occur.

    function Locale_From_UTF8
      (UTF8_String        :        String;
       Bytes_Read         : access Natural;
       Bytes_Written      : access Natural;
       Error              :        GError_Access := null)
       return chars_ptr;

| Same as procedure Locale_From_UTF8, but return the raw C string for efficiency. The caller is responsible for freeing the resulting string. Use the C "free" function to free this.

    function Locale_From_UTF8
      (UTF8_String        :        String)
       return String;

| Same as procedure Locale_From_UTF8, but return only the String.

    function Filename_To_UTF8
      (OS_String          :        String;
       Error              :        GError_Access := null)
       return String;

| Convert a string which is in the encoding used for filenames into a UTF-8 string.

    function Filename_From_UTF8
      (UTF8_String        :        String;
       Error              :        GError_Access := null)
       return String;

| Convert a string from UTF-8 to the encoding used for filenames.

    function Filename_From_URI
      (URI                :        String;
       Hostname           : access chars_ptr;
       Error              :        GError_Access := null)
       return String;

| Convert an escaped UTF-8 encoded URI to a local filename in the encoding used for filenames. URI: A uri describing a filename (escaped, encoded in UTF-8). Hostname: Location to store hostname for the URI. If there is no hostname in the URI, null will be stored in this location. Error: Location to store the error occuring, ignored if null. Any of the errors in Convert_Error_Domain may occur.

    function Filename_To_URI
      (Filename           :        String;
       Hostname           :        String := "";
       Error              :        GError_Access := null)
       return String;

| Convert an absolute filename to an escaped UTF-8 encoded URI. Filename: An absolute filename specified in the encoding used for filenames by the operating system. Hostname: A UTF-8 encoded hostname, or "" for none. Error: Location to store the error occuring, ignored if null. Any of the errors in Convert_Error may occur.
