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, nbytesreturn)
             Display *display;
             int *nbytesreturn;

       char *XFetchBuffer(display, nbytesreturn, buffer)
             Display *display;
             int *nbytesreturn;
             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 X server.

       nbytes    Specifies the number of bytes to be stored.

       nbytesreturn
                 Returns the number of bytes in the buffer.

       rotate    Specifies how much to rotate the cut buffers.

DESCRIPTION
       Note that 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.  Note that
       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.
