Function

GLibconvert

Declaration

gchar*
g_convert (
  const gchar* str,
  gssize len,
  const gchar* to_codeset,
  const gchar* from_codeset,
  gsize* bytes_read,
  gsize* bytes_written,
  GError** error
)

Description

Converts a string from one character set to another.

Note that you should use g_iconv() for streaming conversions. Despite the fact that bytes_read can return information about partial characters, the g_convert_… functions are not generally suitable for streaming. If the underlying converter maintains internal state, then this won’t be preserved across successive calls to g_convert(), g_convert_with_iconv() or g_convert_with_fallback(). (An example of this is the GNU C converter for CP1255 which does not emit a base character until it knows that the next character is not a mark that could combine with the base character.)

Using extensions such as “//TRANSLIT” may not work (or may not work well) on many platforms. Consider using g_str_to_ascii() instead.

Parameters

`str`	An array of `guint8`
	`the string to convert.`
	The length of the array is specified in the `len` argument.
	The data is owned by the caller of the function.
`len`	`gssize`
	The length of the string in bytes, 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)
`to_codeset`	`const gchar*`
	Name of character set into which to convert `str`.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`from_codeset`	`const gchar*`
	Character set of `str`.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`bytes_read`	`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`	`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`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	An array of `guint8`
	If the conversion was successful, a newly allocated buffer containing the converted string, which must be freed with g_free(). Otherwise `NULL` and `error` will be set.
	The length of the array is in the `bytes_written` argument.
	The caller of the function takes ownership of the data, and is responsible for freeing it.
