NAME

       XmGetSecondaryResourceData - A function that provides access to secondary widget resource data

SYNOPSIS

       #include <Xm/Xm.h>

       Cardinal XmGetSecondaryResourceData (widget_class, secondary_data_return)
	       WidgetClass widget_class;
	       XmSecondaryResourceData **secondary_data_return;

DESCRIPTION

       Some  Motif  widget  classes  (such  as	Gadget,  Text,	and VendorShell) have resources that are not accessible via the functions XtGetRe-
       sourceList and XtGetConstraintResourceList. To retrieve the descriptions of these resources,  an  application  must  use  XmGetSecondaryRe-
       sourceData.

       When  a	widget	class  has  such resources, this function provides descriptions of the resources in one or more data structures. XmGetSec-
       ondaryResourceData takes a widget class argument and returns the number of these data structures associated with the widget class.  If  the
       return value is greater than 0, the function allocates and fills an array of pointers to the corresponding data structures. It returns this
       array at the address that is the value of the secondary_data_return argument.

       The type XmSecondaryResourceData is a pointer to a structure with two members that are useful to an application: resources, of  type  XtRe-
       sourceList,  and  num_resources,  of type Cardinal. The resources member is a list of the widget resources that are not accessible using Xt
       functions. The num_resources member is the length of the resources list. If the return value is greater than 0,	XmGetSecondaryResourceData
       allocates  memory  that	the application must free. Use XtFree to free the resource list in each structure (the value of the resources mem-
       ber), the structures themselves, and the array of pointers to the structures (the array with address secondary_data_return).  Specifies the
       widget  class for which secondary resource data is to be retrieved.  Specifies a pointer to an array of XmSecondaryResourceData pointers to
       be returned by this function. If the widget class has no secondary resource data (i.e., if the value returned by the function  is  0),  the
       function returns no meaningful value for this argument.

RETURN VALUES

       Returns the number of secondary resource data structures associated with this widget class.

EXAMPLES

       The following example prints the names of the secondary resources of the Text widget and then frees the data allocated by the function:

       XmSecondaryResourceData * block_array ; Cardinal num_blocks, i, j ; if (num_blocks = XmGetSecondaryResourceData (xmTextWidgetClass,
						    &block_array)) {
	 for (i = 0; i < num_blocks; i++) {
	   for (j = 0 ; j < block_array[i]->num_resources; j++) {
	     printf("%s
", block_array[i]->resources[j].resource_name);
	   }
	   XtFree((char*)block_array[i]->resources);
	   XtFree((char*)block_array[i]);
	 }
	 XtFree((char*)block_array); }
