# Annotation Glossary

### A

allow-none

  NULL is OK, both for passing and for returning.

array

### C

closure

  This parameter is a 'user_data', for callbacks; many bindings can pass NULL here.

### E

element-type

  Generics and defining elements of containers and arrays.

### M

method

  This is a method

### N

nullable

  NULL may be passed as the value in, out, in-out; or as a return value.

### S

scope async

  The callback is valid until first called.

scope call

  The callback is valid only during the call to the method.

Stable

  The intention of a Stable interface is to enable arbitrary third parties to develop applications to these interfaces, release them, and have confidence that they will run on all minor releases of the product (after the one in which the interface was introduced, and within the same major release). Even at a major release, incompatible changes are expected to be rare, and to have strong justifications.

### T

transfer container

  The caller owns the data container, but not the data inside it.

transfer full

  The caller owns the data, and is responsible for free it.

transfer none

  The data is owned by the callee, which is responsible of freeing it.

type

  Override the parsed C type with given type.
