gFileRead {RGtk2} | R Documentation

## gFileRead

### Description

Opens a file for reading. The result is a `GFileInputStream` that can be used to read the contents of the file.

### Usage

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

### Arguments

``object`` | `GFile` to read.
``cancellable`` | a `GCancellable`
`.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.

If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. If the file is a directory, the G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### Value

A list containing the following elements:

`retval` | [`GFileInputStream`] `GFileInputStream` or `NULL` on error.
``error`` | a `GError`, or `NULL`
