Function

GLiblocale_to_utf8

Declaration 

gchar*
g_locale_to_utf8 (
  const gchar* opsysstring,
  gssize len,
  gsize* bytes_read,
  gsize* bytes_written,
  GError** error
)

Description

Converts 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][setlocale] into a UTF-8 string.

If the source encoding is not UTF-8 and the conversion output contains a nul character, the error G_CONVERT_ERROR_EMBEDDED_NUL is set and the function returns NULL. If the source encoding is UTF-8, an embedded nul character is treated with the G_CONVERT_ERROR_ILLEGAL_SEQUENCE error for backward compatibility with earlier versions of this library. Use g_convert() to produce output that may contain embedded nul characters.

Parameters

opsysstring

Type: An array of guint8

A string in the encoding of the current locale. On Windows this means the system codepage.

The length of the array is specified in the len argument.
The data is owned by the caller of the function.
len

Type: gssize

The length of the string, or -1 if the string is nul-terminated (Note that some encodings may allow nul bytes to occur inside strings. In that case, using -1 for the len parameter is unsafe)

bytes_read

Type: gsize*

Location to store the number of bytes in the input string that were successfully converted, or NULL. 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 G_CONVERT_ERROR_ILLEGAL_SEQUENCE occurs, the value stored will be the byte offset after the last valid input sequence.

The argument will be set by the function.
The argument can be NULL.
bytes_written

Type: gsize*

The number of bytes stored in the output buffer (not including the terminating nul).

The argument will be set by the function.
The argument can be NULL.
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 left initialized to NULL by the function 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: gchar*

The converted string, or NULL on an error.

The caller of the function takes ownership of the data, and is responsible for freeing it.
The value is a NUL terminated UTF-8 string.
