This macro is declared in upipe/upipe_helper_uclock.h source file, line 81.

This macro declares four functions dealing with the uclock.

You must add one pointer to your private upipe structure, for instance:

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

• void upipe_foo_init_uclock(struct upipe *upipe)

  Typically called in your upipe_foo_alloc() function.

• int upipe_foo_attach_uclock(struct upipe *upipe)

  Typically called from your upipe_foo_control() handler, such as:

  case UPIPE_ATTACH_UREF_MGR: {
return upipe_foo_attach_uclock(upipe);
}
• int upipe_foo_check_uclock(struct upipe *upipe)

  Checks if the uclock is available, and asks for it otherwise.

• void upipe_foo_clean_uclock(struct upipe *upipe)

  Typically called from your upipe_foo_free() function.

Parameters list:

• STRUCTURE: name of your private upipe structure
• UCLOCK: name of the struct uclock * field of your private upipe structure
