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 XFetchBytes().  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 provided 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 embedded 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.
