                Display *display;
                int *nbytes_return;

          char *XFetchBuffer(display, nbytes_return, buffer)
                Display *display;
                int *nbytes_return;
                int buffer;

                Display *display;
                int rotate;

     ARGUMENTS
          buffer    Specifies the buffer in which you want to store
                    the bytes or from which you want the stored data
                    returned.

          bytes     Specifies the bytes, which are not necessarily
                    ASCII or null-terminated.

          display   Specifies the connection to the X server.

          nbytes    Specifies the number of bytes to be stored.

          nbytes_return
                    Returns the number of bytes in the buffer.

          rotate    Specifies how much to rotate the cut buffers.

     DESCRIPTION
          The data can have embedded null characters and need not be
          null-terminated.  The cut buffer's contents can be retrieved
          later by any client calling XFetchBytes.

          XStoreBytes can generate a BadAlloc error.
          If an invalid buffer is specified, the call has no effect.
          The data can have embedded null characters and need not be
          null-terminated.

          XStoreBuffer can generate a BadAlloc error.

          The XFetchBytes function returns the number of bytes in the
          nbytes_return argument, if the buffer contains data.
          Otherwise, the function returns NULL and sets nbytes 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.

          The XFetchBuffer function returns zero to the nbytes_return
          argument if there is no data in the buffer or if an invalid
          buffer is specified.

          XFetchBuffer can generate a BadValue error.

          The XRotateBuffers function rotates the cut buffers, such
          that buffer 0 becomes buffer n, buffer 1 becomes n + 1 mod
          8, and so on.  This cut buffer numbering is global to the
          display.  Note that XRotateBuffers generates BadMatch errors
          if any of the eight buffers have not been created.

          XRotateBuffers can generate a BadMatch error.

     DIAGNOSTICS
          BadAlloc  The server failed to allocate the requested
                    resource or server memory.

          BadAtom   A value for an Atom argument does not name a
                    defined Atom.

          BadMatch  Some argument or pair of arguments has the correct
                    type and range but fails to match in some other
                    way required by the request.

          BadValue  Some numeric value falls outside the range of
                    values accepted by the request.  Unless a specific
                    range is specified for an argument, the full range
                    defined by the argument's type is accepted.  Any
                    argument defined as a set of alternatives can
                    generate this error.
