NAME

XStoreBytes, XStoreBuffer, XFetchBytes, XFetchBuffer, XRotateBuffers - manipulate cut and paste buffers

SYNTAX

XStoreBytes(display, bytes, nbytes)
      Display *display;
      char *bytes;
      int nbytes;

XStoreBuffer(display, bytes, nbytes, buffer)
      Display *display;
      char *bytes;
      int nbytes;
      int buffer;

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

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

XRotateBuffers(display, rotate)
      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 XWIN 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

     Note that the cut buffer's contents need not be text, so
     zero bytes are not special.  The cut buffer's contents can
     be retrieved later by any client calling XFetchBytes.

XStoreBytes can generate a BadAlloc error.

If the property for the buffer has never been created, a
BadAtom error results.

XStoreBuffer can generate BadAlloc and BadAtom errors.

The XFetchBytes function returns the number of bytes in the
nbytes_return argument, if the buffer contains data.  Other-
wise, 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.  Note that the cut buffer does not
necessarily contain text, so it may contain embedded zero
bytes and may not terminate with a null byte.

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

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 gen-
          erate this error.
