XtAppSetFallbackResources - set fallback resources

void XtAppSetFallbackResources(XtAppContext *app\_context*, String* *specification\_list*);

# [ARGUMENTS](#ARGUMENTS)

[*app\_context*](#app_context)

Specifies the application context.

[*specification\_list*](#specification_list)

Specifies a NULL-terminated list of resource specifications to pre-load the database, or NULL.

# [DESCRIPTION](#DESCRIPTION)

Each entry in *specification\_list* points to a string in the format **XrmPutLineResource**. following a call to **XtAppSetFallbackResources**, when a resource database is being created for a particular screen and the Intrinsics are not able to find or read an application-specific class resource file and if *specification\_list* is not NULL the resource specification in *specification\_list* will be merged into the screen resource database in place of the application-specific class resource file. **XtAppSetFallbackResources** is not required to copy *specification\_list*; the caller must ensure that the contents of the list and the strings addressed by the list remain valid until all displays are initialized or until **XtAppSetFallbackResources** is called again. The value NULL for *specification\_list* removes any previous fallback resource specification for the application context. The intended use for fallback resources is to provide a minimal number of resources that will make the application usable (or at least terminate with helpful diagnostic messages) when some problem exists in finding and loading the application defaults file.
