• UPIPE_HELPER_UREFCOUNT_REAL

This macro is declared in upipe/upipe_helper_urefcount_real.h source file, line 72.

This macro declares functions dealing with public and private parts of the allocated pipe structure.

You must add the urefcount structure to your private pipe structure:

You must also declare UPIPE_HELPER_UPIPE prior to using this macro, and have a function to free the structure when the refcount goes down to 0:

Supposing the name of your structure is upipe_foo and the name of the urefcount is urefcount_real, it declares:

• void upipe_foo_dead_urefcount_real(struct urefcount *urefcount)

  Internal wrapper.

• void upipe_foo_release_urefcount_real(struct urefcount *urefcount)

  Typically called in the main urefcount callback.

• void upipe_foo_init_urefcount_real(struct upipe *upipe)

  Typically called in your upipe_foo_alloc() function.

• void upipe_foo_clean_urefcount_real(struct upipe *upipe)

  Typically called from your upipe_foo_free() function.

Parameter list:

• STRUCTURE: name of your private upipe structure
• UREFCOUNT: name of the struct urefcount field of your private upipe structure
• DEAD: name of the function to free the structure
