XStoreBytes(3X11)		XLIB FUNCTIONS		    XStoreBytes(3X11)



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
       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.

DESCRIPTION
       The data can have embedded null characters and need not be null-termi-
       nated.  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 speci-
       fied.

       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 speci-
		 fied for an argument, the full range defined by the argu-
		 ment’s type is accepted.  Any argument defined as a set of
		 alternatives can generate this error.
