NAME
dce_svc_table - Returns a registered component's subcomponent table
SYNOPSIS
#include <dce/dce.h>
#include <dce/svcremote.h>
void dce_svc_table( dce_svc_string_t component,
dce_svc_subcomparray_t *table,
error_status_t *status );
PARAMETERS
Input
component
The name of the serviceability-registered component, defined
in the component field of the application's sams file.
Output
table An array of elements, each of which describes one of the
component's serviceability sub-components (as defined in its
sams file).
status
Returns the status code from this operation. The status code
is a value that indicates whether the routine completed
successfully and if not, why not.
DESCRIPTION
The dce_svc_table routine returns the serviceability subcomponent
table registered with the specified component. The returned table
consists of an array of elements, each of which describes one sub-
component. Each element consists of four fields, which contain the
sub-component name, its description, its message catalog ID, and the
current value of its debug message level. The first three of these
values are specified in the sams file which is processed during the
application's compilation, and from which the application's message
catalogs and other serviceability and message files are generated.
EXAMPLES
The following code fragment shows how the remote operation might be
called from an application's client side, and how the results might
be printed out:
#include <dce/rpc.h>
#include <dce/service.h>
handle_t svc_bind_handle;
dce_svc_string_t component;
dce_svc_subcomparray_t subcomponents_table;
error_status_t remote_status;
int i;
dce_svc_inq_table( svc_bind_handle,
component,
&subcomponents_table,
&remote_status );
fprintf(stdout, "Subcomponent table size received is: %d...\n",
subcomponents_table.tab_size);
fprintf(stdout, "Subcomponent table contents are:\n");
for (i = 0; i < subcomponents_table.tab_size; i++)
{
fprintf(stdout, "Name: %s\n",
subcomponents_table.table[i].sc_name);
fprintf(stdout, "Desc: %s\n",
subcomponents_table.table[i].sc_descr);
fprintf(stdout, "Msg Cat ID: 0x%8.8lx\n",
(long) subcomponents_table.table[i].sc_descr_msgid);
fprintf(stdout, "Active debug level: %d\n\n",
subcomponents_table.table[i].sc_level);
}
