.SH DESCRIPTION
|
|
The
|
|
.ZN XtAppInitialize
|
|
function calls
|
|
.ZN XtToolkitInitialize
|
|
followed by
|
|
.ZN XtCreateApplicationContext ,
|
|
then calls
|
|
.ZN XtOpenDisplay
|
|
with \fIdisplay_string\fP NULL and \fIapplication_name\fP NULL, and
|
|
finally calls
|
|
.ZN XtAppCreateShell
|
|
with \fIapplication_name\fP NULL, \fIwidget_class\fP
|
|
.ZN applicationShellWidgetClass ,
|
|
and the specified \fIargs\fP and \fInum_args\fP and returns the
|
|
created shell. The modified \fIargc\fP and \fIargv\fP returned by
|
|
.ZN XtDisplayInitialize
|
|
are returned in \fIargc_in_out\fP and \fIargv_in_out\fP. If
|
|
\fIapp_context_return\fP is not NULL, the created application context
|
|
is also returned. If the display specified by the command line cannot
|
|
be opened, an error message is issued and
|
|
.ZN XtAppInitialize
|
|
terminates the application. If \fIfallback_resources\fP is non-NULL,
|
|
.ZN XtAppSetFallbackResources
|
|
is called with the value prior to calling
|
|
.ZN XtOpenDisplay .
|
|
.LP
|
|
XtAppInitialize and XtVaAppInitialize have been superceded by
|
|
.ZN XtOpenApplication
|
|
and
|
|
.ZN XtVaOpenApplication
|
|
respectively.
