Opaque Structures

struct lfds710_stack_state;

Macro

#define LFDS710_STACK_GET_USER_STATE_FROM_STATE( stack_state )

Parameters

stack_state

An initialized struct lfds710_stack_state. Not a pointer to it - the struct itself.

Return Value

Returns a void *, the user_state argument from lfds710_stack_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 <stdio.h>
#include "liblfds710.h"

int main()
{
  char
    stack_name[64] = "Duane Dibbley";

  struct lfds710_stack_state
    ss;

  void
    *user_state;

  lfds710_misc_library_init_valid_on_current_logical_core();

  lfds710_stack_init_valid_on_current_logical_core( &ss, (void *) stack_name );

  user_state = LFDS710_STACK_GET_USER_STATE_FROM_STATE( ss );

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

  lfds710_stack_cleanup( &ss, NULL );

  lfds710_misc_library_cleanup();

  return( EXIT_SUCCESS );
}
