constructor

  This symbol is a constructor, not a static method.

### N

nullable

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

### O

out

  Parameter for returning results. Default is transfer full.

### S

scope call

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

scope notified

  The callback is valid until the GDestroyNotify argument is called.

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 floating

  Alias for transfer none, used for objects with floating refs.

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.
