Functions | |
void * | xbt_dynar_get_ptr (const xbt_dynar_t dynar, const unsigned long idx) |
Retrieve a pointer to the Nth element of a dynar. | |
void * | xbt_dynar_insert_at_ptr (xbt_dynar_t const dynar, const int idx) |
Make room for a new element, and return a pointer to it. | |
void * | xbt_dynar_push_ptr (xbt_dynar_t const dynar) |
Make room at the end of the dynar for a new element, and return a pointer to it. | |
void * | xbt_dynar_pop_ptr (xbt_dynar_t const dynar) |
Mark the last dynar's element as unused and return a pointer to it. |
Those functions do not retrieve the content, but only their address.
void* xbt_dynar_get_ptr | ( | const xbt_dynar_t | dynar, |
const unsigned long | idx | ||
) |
Retrieve a pointer to the Nth element of a dynar.
dynar | information dealer |
idx | index of the slot we want to retrieve |
void* xbt_dynar_insert_at_ptr | ( | xbt_dynar_t const | dynar, |
const int | idx | ||
) |
Make room for a new element, and return a pointer to it.
You can then use regular affectation to set its value instead of relying on the slow memcpy. This is what xbt_dynar_insert_at_as() does.
void* xbt_dynar_push_ptr | ( | xbt_dynar_t const | dynar | ) |
Make room at the end of the dynar for a new element, and return a pointer to it.
You can then use regular affectation to set its value instead of relying on the slow memcpy. This is what xbt_dynar_push_as() does.
void* xbt_dynar_pop_ptr | ( | xbt_dynar_t const | dynar | ) |
Mark the last dynar's element as unused and return a pointer to it.
You can then use regular affectation to set its value instead of relying on the slow memcpy. This is what xbt_dynar_pop_as() does.
