Opaque Structures

struct lfds711_list_aso_state;

Macro

#define LFDS711_LIST_ASO_GET_USER_STATE_FROM_STATE( list_aso_state )

Parameters

list_aso_state

An initialized struct lfds711_list_aso_state. Not a pointer to it - the struct itself.

Return Value

Returns a void *, the user_state argument from lfds711_list_aso_init_valid_on_current_logical_core.

Notes

The user state value can only be set the once, when the data structure instance is initialized.

As with all liblfds macros, the macro operates on the structure itself, not a pointer to it.

Example

#include "liblfds711.h"
#include <stdio.h>
#include <string.h>

int main()
{
  char
    list_aso_name[64] = "Bring It On";

  struct lfds711_list_aso_state
    laso;

  void
    *user_state;

  lfds711_misc_library_init_valid_on_current_logical_core();

  lfds711_list_aso_init_valid_on_current_logical_core( &laso, strcmp, LFDS711_LIST_ASO_EXISTING_KEY_FAIL, (void *) list_aso_name );

  user_state = LFDS711_LIST_ASO_GET_USER_STATE_FROM_STATE( laso );

  printf( "list_aso name is \"%s\"\n", (char *) user_state );

  lfds711_list_aso_cleanup( &laso, NULL );

  lfds711_misc_library_cleanup();

  return( EXIT_SUCCESS );
}
