gDataInputStreamReadLine {RGtk2} | R Documentation

## gDataInputStreamReadLine

### Description

Reads a line from the data input stream.

### Usage

    gDataInputStreamReadLine(object, cancellable = NULL, .errwarn = TRUE)

### Arguments

``object`` | a given `GDataInputStream`.
``cancellable`` | optional `GCancellable` object, `NULL` to ignore.
`.errwarn` | Whether to issue a warning on error or fail silently

### Details

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.

### Value

A list containing the following elements:

`retval` | [char] a string with the line that was read in (without the newlines). Set `length` to a `numeric` 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.
``length`` | a `numeric` to get the length of the data read in.
``error`` | `GError` for error reporting.
