struct lfds700_btree_au_state;
Macro
#define LFDS700_BTREE_AU_GET_USER_STATE_FROM_STATE( btree_au_state )
Parameters
btree_au_state
- An initialized struct lfds700_btree_au_state. Not a pointer to it - the struct itself.
Return Value
Returns a void *, the user_state argument from lfds700_btree_au_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 "liblfds700.h" int main() { char btree_name[64] = "Staggerlee"; struct lfds700_btree_au_state baus; void *user_state; lfds700_misc_library_init_valid_on_current_logical_core(); lfds700_btree_au_init_valid_on_current_logical_core( &baus, strcmp, LFDS700_BTREE_AU_LINK_RESULT_SUCCESS_OVERWRITE, (void *) btree_name ); user_state = LFDS700_BTREE_AU_GET_USER_STATE_FROM_STATE( baus ); printf( "btree name is \"%s\"\n", (char *) user_state ); lfds700_btree_au_cleanup( &baus, NULL ); lfds700_misc_library_cleanup(); return( EXIT_SUCCESS ); }
