Method

GioDataInputStreamread_line

Declaration

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

Description

Reads a line from the data input stream. Note that no encoding checks or conversion is performed; the input is not guaranteed to be UTF-8, and may in fact have embedded NUL characters.

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.

Parameters

length 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 GCancellable
 

Optional GCancellable object, NULL to ignore.

 The argument can be NULL.
 The data is owned by the caller of the function.
error GError **
  The return location for a GError*, or NULL.

Return value

Returns: An array of guint8
 

a NUL terminated byte array 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. If there’s no content to read, it will still return NULL, but error won’t be set.

 The array is NULL-terminated.
 The caller of the method takes ownership of the data, and is responsible for freeing it.
 The return value can be NULL.
