dag_config_set_boolean_attribute(3)

NAME
dag_config_set_boolean_attribute. sets the value of a boolean attribute.

SYNOPSIS
#include "dag_config.h "

dag_err_t
dag_config_set_boolean_attribute(dag_card_ref_t card, attr_uuid_t uuid,uint8_t value);.

DESCRIPTION
dag_config_set_boolean_attribute is passed the reference to the DAG card and the attribute idendifier,and the value to be set and returns kDagErrNone on success.

RETURN VALUE
returns kDagErrNone on success and kDagErrInvalidCardRef if the card reference is invalid.

EXAMPLES
The following program illustrates how the function is used. It configures all ports on the card in fcl mode.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_attribute_uuid(port,
         kBooleanAttributeFacilityLoopback);
          /* Read and display the value of the attribute. */
          val = (uint8_t) dag_config_set_boolean_attribute(card_ref,
           active_uuid,1);
   }
   /* Dispose of the card. */
   dag_config_dispose(card_ref);
   return EXIT_SUCCESS;
 }
