dag_component_get_config_attribute_count(3)

NAME
dag_component_get_config_attribute_count retrieves the number of configurable attributes in a given component of a DAG card.

SYNOPSIS
#include "dag_config.h "

int
dag_component_get_config_attribute_count(dag_component_t component);

DESCRIPTION
dag_component_get_attribute_count returns the number of configurable attributes in a given component of a DAG card.

EXAMPLES
The following program illustrates how the function is used. It queries the active attributes of all ports on the card and displays the result. For the sake of clarity the error-handling code has been omitted from this example. int main(int argc, const char* argv[]) {

   dag_card_ref_t card_ref = NULL;
   dag_component_t root_component = NULL;
   uint32_t count;
   uint32_t i;

   /* Get a reference to the card. */
   card_ref = dag_config_init("/dev/dag0");
   /* Get a reference to the root component. */
   root_component = dag_config_get_root_component(card_ref);
   /* Find out how many ports the card has. */
   count = dag_component_get_subcomponent_count_of_type(root_component,
   kComponentPort);

   for (i = 0; i < count; i++)
   {
          dag_component_t port = NULL;
          attr_uuid_t active_uuid = 0;
          uint8_t val = 0;
          /* Get a reference to the port. */
          port = dag_component_get_subcomponent(root_component,
            kComponentPort, i);
          /* Get a reference to the active attribute of the port. */
          active_uuid = dag_component_get_config_attribute_uuid(port,
         kBooleanAttributeActive);
          /* Read and display the value of the attribute. */
          val = (uint8_t) dag_config_get_boolean_attribute(card_ref,
           active_uuid);
          printf("Port %u active = %u, i, val);
   }
   /* Dispose of the card. */
   dag_config_dispose(card_ref);
   return EXIT_SUCCESS; }

RETURN VALUE
The number of configurable attributes in that component.
