XmGetSecondaryResourceData(Library Functions ManuXmGetSecondaryResourceData(3)

       XmGetSecondaryResourceData  --  A function that provides	access to sec-
       ondary widget resource data

       #include	<Xm/Xm.h>
       Cardinal	XmGetSecondaryResourceData(
       WidgetClass widget_class,
       XmSecondaryResourceData **secondary_data_return);

       Some Motif widget classes (such as Gadget, Text,	and VendorShell)  have
       resources  that	are  not  accessible  through  the  functions XtGetRe-
       sourceList and XtGetConstraintResourceList.  In order to	 retrieve  the
       descriptions  of	 these	resources,  an	application must use XmGetSec-

       When a widget class has such resources, this function provides descrip-
       tions  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 re-
       turn value is greater than 0 (zero), 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_re-
       turn 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

       If the return value is greater than 0  (zero),  XmGetSecondaryResource-
       Data  allocates	memory	that the application must free.	 Use XtFree to
       free the	resource list in each structure	(the value  of	the  resources
       member),	 the  structures  themselves, and the array of pointers	to the
       structures (the array whose address is 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, for example,	if the
		 value returned	by the function	is 0 (zero), the function  re-
		 turns no meaningful value for this argument.

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

       The following example  uses  XmGetSecondaryResourceData	to  print  the
       names  of  the  secondary  resources  of	the Motif 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\n", block_array[i]->resources[j].resource_name);
