NAME

       XmGetSecondaryResourceData  — A function that provides access to secondary widget resource
       data "XmGetSecondaryResourceData"

SYNOPSIS

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

DESCRIPTION

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

       When  a  widget  class  has  such  resources,  this  function provides descriptions of the
       resources in one or more data structures.  XmGetSecondaryResourceData 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 (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_return argument.

       The type XmSecondaryResourceData is a pointer to a structure with  two  members  that  are
       useful  to  an  application: resources, of type XtResourceList, 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 (zero), XmGetSecondaryResourceData 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).

       widget_class
                 Specifies the widget class for which secondary resource data is to be retrieved.

       secondary_data_return
                 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
                 returns no meaningful value for this argument.

RETURN

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

EXAMPLE

       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);
           }
           XtFree((char*)block_array[i]->resources);
           XtFree((char*)block_array[i]);
         }
         XtFree((char*)block_array);
       }

                                                                    XmGetSecondaryResourceData(3)
