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