ARGUMENTS
app_context
If non-NULL, returns the application context.
app_class Specifies the class name of the application.
options Specifies the command line options table.
num_options
Specifies the number of entries in options list.
argc Specifies the number of command line arguments.
argv Specifies a list of command line arguments.
fallbacks Specifies a null-terminated list of resource specifications,
or NULL.
args Specifies an argument list used to override default values.
num_args Specifies the number of entries in the argument list.
DESCRIPTION
The function performs the following operations:
· Initializes the X Tookkit Intrinsics library by calling
· Creates an application context by calling
· Creates a set of fallback resources by calling with fallbacks if
it in non-NULL.
· Opens and initializes a display by calling with a display_name
of NULL and an application_name of NULL.
· Calls with an application_name of NULL, a widget_class of appli‐
cationShellWidgetClass, and the specified args and num_args.
The function returns the ID of the newly created shell widget. The
modified values returned by for argc and argv are returned to the call‐
er. If app_context is not NULL, the application context created by is
also returned. If the display specified by the command line cannot be
opened, an error message is issued and the application is terminated.
