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.

destructor_fn

ao2_destructor_fn destructor_fn

Definition at line 55 of file astobj2.c.

Referenced by __ao2_ref(), and internal_ao2_alloc().

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.

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.

ref_counter

int32_t ref_counter

Number of references held for this object

void* weakptr

This field is used for astobj2 and ao2_weakproxy objects to reference each other
