Generates XML for annotated widgets

char *sm_xml_export();

char *sm_n_xml_export(char *gsd);

char *sm_obj_xml_export(int *objid);

gsd

An expression indicating the screen or LDB to use for XML generation. For example, @screen_num(-1) specifies the next to top screen on the form stack, and @ldb("customer_xml.scr") specifies the customer_xml.scr screen in the LDB.

objid

An object id indicating the screen or LDB to use for XML generation.

• · Success: A character string containing the generated XML

• · Failure: Null pointer

The sm_*xml_export functions generate XML for the specified screen. You can call sm_xml_export to generate XML for the current screen.

In order to be included in the XML, widgets must have the xml_tag property specified. In addition, the screen must have a value in the xml_tag property or both the xml_prefix and xml_postfix properties. For more information on using these functions, see Chapter 22, "Using XML Data," in the Application Development Guide.

Do not call sm_ffree to free the returned value. This value will be freed on the next call to one of these functions.
