-.SH DESCRIPTION
-The application programming library for the
-\fIX11 Double-Buffering, Multi-Buffering, and Stereo Extension\fP
-contains the interfaces described below.
-With the exception of
-.ZN XmbufQueryExtension ,
-if any of these routines are
-called with a display that does not support the extension, the
-ExtensionErrorHandler (which can be set with
-.ZN XSetExtensionErrorHandler
-and functions the same way as
-.ZN XSetErrorHandler )
-will be called and the function will then return.
-.PP
-.ZN XmbufQueryExtension
-returns
-.ZN True
-if the multibuffering/stereo
-extension is available on the
-given display. If the extension exists, the value of the first event
-code (which should be added to the event type constants
-.ZN MultibufferClobberNotify
-and
-.ZN MultibufferUpdateNotify
-to get the actual
-values) is stored into event_base_return and the value of the first
-error code (which should be added to the error type constant
-.ZN MultibufferBadBuffer
-to get the actual value) is stored into error_base_return.
-.PP
-.ZN XmbufGetVersion
-gets the major and minor version numbers of the extension.
-The return
-value is zero if an error occurs or non-zero if no error happens.
-.PP
-.ZN XmbufCreateBuffers
-requests that "count" buffers be
-created with the given update_action
-and update_hint and be associated with the indicated window. The
-number of buffers created is returned (zero if an error occurred)
-and buffers_update is filled in with that many Multibuffer identifiers.
-.PP
-.ZN XmbufDestroyBuffers
-destroys the buffers associated
-with the given window.
-.PP
-.ZN XmbufDisplayBuffers
-displays the indicated buffers their
-appropriate windows within
-max_delay milliseconds after min_delay milliseconds have passed.
-No two buffers may be associated with the same window or else a Match
-error is generated.
-.PP
-.ZN XmbufGetWindowAttributes
-gets the multibuffering attributes that apply
-to all buffers associated
-with the given window.
-The list of buffers returns may be freed with
-.ZN XFree .
-Returns non-zero on success and zero if an error occurs.
-.PP
-.ZN XmbufChangeWindowAttributes
-sets the multibuffering attributes
-that apply to all buffers associated
-with the given window. This is currently limited to the update_hint.
-.PP
-.ZN XmbufGetBufferAttributes
-gets the attributes for the indicated buffer.
-Returns non-zero on
-success and zero if an error occurs.
-.PP
-.ZN XmbufChangeBufferAttributes
-sets the attributes for the indicated buffer.
-This is currently limited to the event_mask.
-.PP
-.ZN XmbufGetScreenInfo
-gets the parameters controlling how
-mono and stereo windows may be
-created on the screen of the given drawable. The numbers of sets of
-visual and depths are returned in nmono_return and nstereo_return. If
-nmono_return is greater than zero, then mono_info_return is set to the
-address of an array of
-.ZN XmbufBufferInfo
-structures describing the
-various visuals and depths that may be used. Otherwise,
-mono_info_return is set to NULL. Similarly, stereo_info_return is set
-according to nstereo_return. The storage returned in mono_info_return
-and stereo_info_return may be released by
-.ZN XFree .
-If no errors are
-encounted, non-zero will be returned.
-.PP
-.ZN XmbufCreateStereoWindow
-creates a stereo window in the same way that
-.ZN XCreateWindow
-creates a mono window. The buffer ids for the left and right buffers are
-returned in left_return and right_return, respectively. If an
-extension error handler that returns is installed,
-.ZN None
-will be returned if the extension is not available on this display.

+The application programming library for the

+contains the interfaces described below.
+With the exception of
+.ZN XmbufQueryExtension ,
+if any of these routines are
+called with a display that does not support the extension, the
+ExtensionErrorHandler (which can be set with
+.ZN XSetExtensionErrorHandler
+and functions the same way as
+.ZN XSetErrorHandler )
+will be called and the function will then return.
+.PP
+.ZN XmbufQueryExtension
+returns
+.ZN True
+if the multibuffering/stereo
+extension is available on the
+given display. If the extension exists, the value of the first event
+code (which should be added to the event type constants
+.ZN MultibufferClobberNotify
+and
+.ZN MultibufferUpdateNotify
+to get the actual
+values) is stored into event_base_return and the value of the first
+error code (which should be added to the error type constant
+.ZN MultibufferBadBuffer
+to get the actual value) is stored into error_base_return.
+.PP
+.ZN XmbufGetVersion
+gets the major and minor version numbers of the extension.
+The return
+value is zero if an error occurs or non-zero if no error happens.
+.PP
+.ZN XmbufCreateBuffers
+requests that "count" buffers be
+created with the given update_action
+and update_hint and be associated with the indicated window. The
+number of buffers created is returned (zero if an error occurred)
+and buffers_update is filled in with that many Multibuffer identifiers.
+.PP
+.ZN XmbufDestroyBuffers
+destroys the buffers associated
+with the given window.
+.PP
+.ZN XmbufDisplayBuffers
+displays the indicated buffers their
+appropriate windows within
+max_delay milliseconds after min_delay milliseconds have passed.
+No two buffers may be associated with the same window or else a Match
+error is generated.
+.PP
+.ZN XmbufGetWindowAttributes
+gets the multibuffering attributes that apply
+to all buffers associated
+with the given window.
+The list of buffers returns may be freed with
+.ZN XFree .
+Returns non-zero on success and zero if an error occurs.
+.PP
+.ZN XmbufChangeWindowAttributes
+sets the multibuffering attributes
+that apply to all buffers associated
+with the given window. This is currently limited to the update_hint.
+.PP
+.ZN XmbufGetBufferAttributes
+gets the attributes for the indicated buffer.
+Returns non-zero on
+success and zero if an error occurs.
+.PP
+.ZN XmbufChangeBufferAttributes
+sets the attributes for the indicated buffer.
+This is currently limited to the event_mask.
+.PP
+.ZN XmbufGetScreenInfo
+gets the parameters controlling how
+mono and stereo windows may be
+created on the screen of the given drawable. The numbers of sets of
+visual and depths are returned in nmono_return and nstereo_return. If
+nmono_return is greater than zero, then mono_info_return is set to the
+address of an array of
+.ZN XmbufBufferInfo
+structures describing the
+various visuals and depths that may be used. Otherwise,
+mono_info_return is set to NULL. Similarly, stereo_info_return is set
+according to nstereo_return. The storage returned in mono_info_return
+and stereo_info_return may be released by
+.ZN XFree .
+If no errors are
+encounted, non-zero will be returned.
+.PP
+.ZN XmbufCreateStereoWindow
+creates a stereo window in the same way that
+.ZN XCreateWindow
+creates a mono window. The buffer ids for the left and right buffers are
+returned in left_return and right_return, respectively. If an
+extension error handler that returns is installed,
+.ZN None
+will be returned if the extension is not available on this display.
