NAME

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

SYNTAX

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

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

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

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

       int XRotateBuffers(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.
