Detailed Description

astobj2 objects are always preceded by this data structure, which contains a reference counter, option flags and a pointer to a destructor. The refcount is used to decide when it is time to invoke the destructor. The magic number is used for consistency check.

◆ lockused

uint32_t lockused

Set to 1 when the lock is used if refdebug is enabled.

Note
This bit-field may be modified after object creation. It shares a uint32_t with options and magic.

◆ magic

uint32_t magic

◆ options

uint32_t options

The ao2 object option flags.

Note
This field is constant after object creation. It shares a uint32_t with lockused and magic.
