Function

GLibfilename_to_utf8

Declaration [src]

gchar*
g_filename_to_utf8 (
  const gchar* opsysstring,
  gssize len,
  gsize* bytes_read,
  gsize* bytes_written,
  GError** error
)

Description [src]

Converts a string which is in the encoding used by GLib for filenames into a UTF-8 string. Note that on Windows GLib uses UTF-8 for filenames; on other platforms, this function indirectly depends on the [current locale][setlocale].

The input string shall not contain nul characters even if the len argument is positive. A nul character found inside the string will result in error G_CONVERT_ERROR_ILLEGAL_SEQUENCE. 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. Use g_convert() to produce output that may contain embedded nul characters.

Parameters

opsysstring const gchar*
 

A string in the encoding for filenames.

 The data is owned by the caller of the function.
 The string is a file system path, using the OS encoding.
len 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 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.
 The called function takes ownership of the data, and is responsible for freeing it.
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.
 The called function takes ownership of the data, and is responsible for freeing it.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: 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 string is a NUL terminated UTF-8 string.
