lfds700_list_addonly_ordered_singlylinked.h
Opaque Structures
struct lfds700_list_aos_state;
Macro
#define LFDS700_LIST_AOS_GET_USER_STATE_FROM_STATE( list_aos_state )
Parameters
list_aos_state
- An initialized struct lfds700_list_aos_state. Not a pointer to it - the struct itself.
Return Value
Returns a void *, the user_state argument from lfds700_list_aos_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 "liblfds700.h"
#include <stdio.h>
#include <string.h>
int main()
{
char
list_aos_name[64] = "Bring It On";
struct lfds700_list_aos_state
laos;
void
*user_state;
lfds700_misc_library_init_valid_on_current_logical_core();
lfds700_list_aos_init_valid_on_current_logical_core( &laos, strcmp, LFDS700_LIST_AOS_EXISTING_KEY_FAIL, (void *) list_aos_name );
user_state = LFDS700_LIST_AOS_GET_USER_STATE_FROM_STATE( laos );
printf( "list_aos name is \"%s\"\n", (char *) user_state );
lfds700_list_aos_cleanup( &laos, NULL );
lfds700_misc_library_cleanup();
return( EXIT_SUCCESS );
}
