|
.SH DESCRIPTION
|
|
|
|
The
|
|
|
|
.ZN XAllocClassHint
|
|
|
|
function allocates and returns a pointer to a
|
|
|
|
.ZN XClassHint
|
|
|
|
structure.
|
|
|
|
Note that the pointer fields in the
|
|
|
|
.ZN XClassHint
|
|
|
|
structure are initially set to NULL.
|
|
|
|
If insufficient memory is available,
|
|
|
|
.ZN XAllocClassHint
|
|
|
|
returns NULL.
|
|
|
|
To free the memory allocated to this structure,
|
|
|
|
use
|
|
|
|
.ZN XFree .
|
|
|
|
.LP
|
|
|
|
The
|
|
|
|
.ZN XSetClassHint
|
|
|
|
function sets the class hint for the specified window.
|
|
|
|
If the strings are not in the Host Portable Character Encoding,
|
|
|
|
the result is implementation-dependent.
|
|
|
|
.LP
|
|
|
|
.ZN XSetClassHint
|
|
|
|
can generate
|
|
|
|
.ZN BadAlloc
|
|
|
|
and
|
|
|
|
.ZN BadWindow
|
|
|
|
errors.
|
|
|
|
.LP
|
|
|
|
The
|
|
|
|
.ZN XGetClassHint
|
|
|
|
function returns the class hint of the specified window to the members
|
|
|
|
of the supplied structure.
|
|
|
|
If the data returned by the server is in the Latin Portable Character Encoding,
|
|
|
|
then the returned strings are in the Host Portable Character Encoding.
|
|
|
|
Otherwise, the result is implementation-dependent.
|
|
|
|
It returns a nonzero status on success;
|
|
|
|
otherwise, it returns a zero status.
|
|
|
|
To free res_name and res_class when finished with the strings,
|
|
|
|
use
|
|
|
|
.ZN XFree
|
|
|
|
on each individually.
|
|
|
|
.LP
|
|
|
|
.ZN XGetClassHint
|
|
|
|
can generate a
|
|
|
|
.ZN BadWindow
|
|
|
|
error.
|
|
|
|
.SH PROPERTIES
|
|
|
|
.TP 1i
|
|
|
|
\s-1WM_CLASS\s+1
|
|
|
|
Set by application programs to allow window and session
|
|
|
|
managers to obtain the application's resources from the resource database.
|
|
|
|
.SH STRUCTURES
|
|
|
|
The
|
|
|
|
.ZN XClassHint
|
|
|
|
structure contains:
|
|
|
|
.LP
|
|
|
|
.IN "XClassHint" "" "@DEF@"
|
|
|
|
.Ds 0
|
|
|
|
typedef struct {
|
2013-04-28 10:55:55 -06:00
|
|
|
char *res_name;
|
|
|
|
char *res_class;
|
2006-11-25 09:33:55 -07:00
|
|
|
} XClassHint;
|
|
|
|
.LP
|
|
|
|
The res_name member contains the application name,
|
|
|
|
and the res_class member contains the application class.
|
|
|
|
Note that the name set in this property may differ from the name set as WM_NAME.
|
|
|
|
That is, WM_NAME specifies what should be displayed in the title bar and,
|
|
|
|
therefore, can contain temporal information (for example, the name of
|
|
|
|
a file currently in an editor's buffer).
|
|
|
|
On the other hand,
|
|
|
|
the name specified as part of WM_CLASS is the formal name of the application
|
|
|
|
that should be used when retrieving the application's resources from the
|
|
|
|
resource database.
|
|
|
|
.SH DIAGNOSTICS
|
|
|
|
.TP 1i
|
|
|
|
.ZN BadAlloc
|
|
|
|
The server failed to allocate the requested resource or server memory.
|
|
|
|
.TP 1i
|
|
|
|
.ZN BadWindow
|
|
|
|
A value for a Window argument does not name a defined Window.
