XFetchBytes()							 XFetchBytes()

Name
  XFetchBytes – return data from cut buffer 0.

Synopsis
  char *XFetchBytes(display, nbytes_return)
	Display *display;
	int *nbytes_return;

Arguments
  display   Specifies	a  connection  to  an  X  server;  returned  from
	    XOpenDisplay().

  nbytes_return
	    Returns the number of bytes in the string returned by XFetch‐
	    Bytes().   If  there is no data in the buffer, *nbytes_return
	    is set to 0.

Returns
  The buffer data.

Description
  XFetchBytes() returns data from cut buffer 0 of the eight buffers  pro‐
  vided	 for  interclient  communication.   If	the buffer contains data,
  XFetchBytes() returns the number of bytes in	nbytes_return,	otherwise
  it  returns  NULL and sets *nbytes_return to 0.  The appropriate amount
  of storage is allocated and the pointer returned; the client must  free
  this	storage	 when finished with it by calling XFree().  Note that the
  cut buffer does not necessarily contain text, so it may contain  embed‐
  ded null bytes and may not terminate with a null byte.

  Use XFetchBuffer() to fetch data from any specified cut buffer.

  Selections are preferred over cut buffers as a communication method.

  For  more information on cut buffers, see Volume One, Chapter 15, Other
  Programming Techniques.
