DESCRIPTION

54       By  convention, X applications use a standard string to indicate window
55       size and placement.  XParseGeometry makes it easier to conform to  this
56       standard  because  it allows you to parse the standard window geometry.
57       Specifically, this function lets you parse strings of the form:
58
59       [=][<width>{xX}<height>][{+-}<xoffset>{+-}<yoffset>]
60
61       The fields map  into  the  arguments  associated  with  this  function.
62       (Items enclosed in <> are integers, items in [] are optional, and items
63       enclosed in {} indicate “choose one of.”  Note that the brackets should
64       not  appear  in  the  actual string.)  If the string is not in the Host
65       Portable Character Encoding, the result is implementation-dependent.
66
67       The XParseGeometry function returns a bitmask that indicates  which  of
68       the  four  values  (width,  height, xoffset, and yoffset) were actually
69       found in the string and whether the x and y values  are  negative.   By
70       convention, -0 is not equal to +0, because the user needs to be able to
71       say “position the window relative to the right or  bottom  edge.”   For
72       each  value  found,  the  corresponding  argument is updated.  For each
73       value not found, the argument is left unchanged.  The bits  are  repre‐
74       sented by XValue, YValue, WidthValue, HeightValue, XNegative, or YNega‐
75       tive and are defined in X11/Xutil.h.  They will be set whenever one  of
76       the values is defined or one of the signs is set.
77
78       If  the  function  returns either the XValue or YValue flag, you should
79       place the window at the requested position.
80
81       The XWMGeometry function combines any geometry  information  (given  in
82       the  format  used  by  XParseGeometry) specified by the user and by the
83       calling program with size hints (usually  the  ones  to  be  stored  in
84       WM_NORMAL_HINTS)  and  returns  the position, size, and gravity (North‐
85       WestGravity, NorthEastGravity, SouthEastGravity,  or  SouthWestGravity)
86       that  describe  the  window.  If the base size is not set in the XSize‐
87       Hints structure, the minimum size is used if set.   Otherwise,  a  base
88       size of zero is assumed.  If no minimum size is set in the hints struc‐
89       ture, the base size is used.  A mask (in the form returned by XParseGe‐
90       ometry)  that  describes  which values came from the user specification
91       and whether or not the position coordinates are relative to  the  right
92       and  bottom  edges  is returned.  Note that these coordinates will have
93       already been accounted for in the x_return and y_return values.
94
95       Note that invalid geometry specifications can cause a width  or  height
96       of  zero  to be returned.  The caller may pass the address of the hints
97       win_gravity field as gravity_return to update the hints directly.
