Declaration [src]

char*
g_data_input_stream_read_line_utf8 (
  GDataInputStream* stream,
  gsize* length,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Reads a UTF-8 encoded line from the data input stream.

If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned.

Available since: 2.30

Parameters

length

Type: gsize*

A #gsize to get the length of the data read in.

The argument will be set by the function.

The argument can be NULL.

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

The argument can be NULL.

The data is owned by the caller of the method.

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: char*

A NUL terminated UTF-8 string with the line that was read in (without the newlines). Set length to a #gsize to get the length of the read line. On an error, it will return NULL and error will be set. For UTF-8 conversion errors, the set error domain is G_CONVERT_ERROR. If there’s no content to read, it will still return NULL, but error won’t be set.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.

The return value can be NULL.

The value is a NUL terminated UTF-8 string.
