+.SH DESCRIPTION
+The
+.ZN XAllocSizeHints
+function allocates and returns a pointer to a
+.ZN XSizeHints
+structure.
+Note that all fields in the
+.ZN XSizeHints
+structure are initially set to zero.
+If insufficient memory is available,
+.ZN XAllocSizeHints
+returns NULL.
+To free the memory allocated to this structure,
+use
+.ZN XFree .
+.LP
+The
+.ZN XSetWMNormalHints
+function replaces the size hints for the WM_NORMAL_HINTS property
+on the specified window.
+If the property does not already exist,
+.ZN XSetWMNormalHints
+sets the size hints for the WM_NORMAL_HINTS property on the specified window.
+The property is stored with a type of WM_SIZE_HINTS and a format of 32.
+.LP
+.ZN XSetWMNormalHints
+can generate
+.ZN BadAlloc
+and
+.ZN BadWindow
+errors.
+.LP
+The
+.ZN XGetWMNormalHints
+function returns the size hints stored in the WM_NORMAL_HINTS property
+on the specified window.
+If the property is of type WM_SIZE_HINTS, is of format 32,
+and is long enough to contain either an old (pre-ICCCM)
+or new size hints structure,
+.ZN XGetWMNormalHints
+sets the various fields of the
+.ZN XSizeHints
+structure, sets the supplied_return argument to the list of fields
+that were supplied by the user (whether or not they contained defined values),
+and returns a nonzero status.
+Otherwise, it returns a zero status.
+.LP
+If
+.ZN XGetWMNormalHints
+returns successfully and a pre-ICCCM size hints property is read,
+the supplied_return argument will contain the following bits:
+.LP
+.Ds
+(USPosition|USSize|PPosition|PSize|PMinSize|
+ PMaxSize|PResizeInc|PAspect)

+If the property is large enough to contain the base size

+The

+.LP
+The x, y, width, and height members are now obsolete
+and are left solely for compatibility reasons.
+The min_width and min_height members specify the
+minimum window size that still allows the application to be useful.
+The max_width and max_height members specify the maximum window size.
+The width_inc and height_inc members define an arithmetic progression of
+sizes (minimum to maximum) into which the window prefers to be resized.
+The min_aspect and max_aspect members are expressed
+as ratios of x and y,
+and they allow an application to specify the range of aspect
+ratios it prefers.
+The base_width and base_height members define the desired size of the window.
+The window manager will interpret the position of the window
+and its border width to position the point of the outer rectangle
+of the overall window specified by the win_gravity member.
+The outer rectangle of the window includes any borders or decorations
+supplied by the window manager.
+In other words,
+if the window manager decides to place the window where the client asked,
+the position on the parent window's border named by the win_gravity
+will be placed where the client window would have been placed
+in the absence of a window manager.
+.LP
+Note that use of the
+.ZN PAllHints
+macro is highly discouraged.
