NAME

SYNOPSIS
Status XGetWMNormalHints(display, w, hints_return, \ supplied_return)
Display ∗display;
Window w;
XSizeHints ∗hints_return;
long ∗supplied_return;
ARGUMENTS
displaySpecifies a connection to an X server; returned from XOpenDisplay().
wSpecifies the window.
hints_return
Returns the size hints for the window in its normal state.
supplied_return
Returns the hints that were supplied by the user.
RETURNS
Zero on failure, non-zero on success.
AVAILABILITY
Release 4 and later.
DESCRIPTION
XGetWMNormalHints() returns the size hints stored in the XA_WM_NORMAL_HINTS property on the specified window. If the property is of type XA_WM_SIZE_HINTS, of format 32, and is long enough to contain either an old (pre-ICCCM) or new size hints structure, XGetWMNormalHints() sets the various fields of the 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 non-zero status. XGetWMNormalHints() returns a zero status if the application specified no normal size hints for this window.
XGetWMNormalHints() supersedes XGetNormalHints().
If XGetWMNormalHints() returns successfully and a pre-ICCCM size hints property is read, the supplied_return argument will contain the following bits: (USPosition|USSize|PPosition|PSize|PMinSize|PMaxSize|PResizeInc|PAspect) If the property is large enough to contain the base size and window gravity fields as well, the supplied argument will also contain the following bits: (PBaseSize|PWinGravity) This function is normally used only by a window manager.
