gBufferedInputStreamReadByte {RGtk2} | R Documentation

## gBufferedInputStreamReadByte

### Description

Tries to read a single byte from the stream or the buffer. Will block during this read.

### Usage

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

### Arguments

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

### Details

On success, the byte read from the stream is returned. On end of stream -1 is returned but it's not an exceptional error and `error` is not set.

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 an operation was partially finished when the operation was cancelled the partial result will be returned, without an error.

On error -1 is returned and `error` is set accordingly.

### Value

A list containing the following elements:

`retval` | [integer] the byte read from the `stream`, or -1 on end of stream or error.
``error`` | location to store the error occuring, or `NULL` to ignore.
