Method

GioBufferedInputStreamread_byte

Declaration

int
g_buffered_input_stream_read_byte (
  GBufferedInputStream* stream,
  GCancellable* cancellable,
  GError** error
)

Description

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

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.

Parameters

`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:	`int`
	The byte read from the `stream`, or -1 on end of stream or error.
