Macro
#define LFDS700_QUEUE_BSS_GET_USER_STATE_FROM_STATE( queue_bss_state )
Parameters
queue_bss_state
- An initialized struct lfds700_queue_bss_state. Not a pointer to it - the struct itself.
Return Value
Returns a void *, the user_state argument from lfds700_queue_bss_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
queue_bss_name[64] = "Idiot Prayer";
struct lfds700_queue_bss_element
element_array[64];
struct lfds700_queue_bss_state
qbsss;
void
*user_state;
lfds700_misc_library_init_valid_on_current_logical_core();
lfds700_queue_bss_init_valid_on_current_logical_core( &qbsss, element_array, 64, (void *) queue_bss_name );
user_state = LFDS700_QUEUE_BSS_GET_USER_STATE_FROM_STATE( qbsss );
printf( "queue_bss name is \"%s\"\n", (char *) user_state );
lfds700_queue_bss_cleanup( &qbsss, NULL );
lfds700_misc_library_cleanup();
return( EXIT_SUCCESS );
