DESCRIPTION

An nng_duration is a relative time, measured in milliseconds. This type is most often used in conjunction with timers and timeouts.

A couple of special values have been set aside, and carry special meanings.

NNG_DURATION_DEFAULT

Indicates a context-specific default value should be used.

NNG_DURATION_INFINITE

Effectively an infinite duration; used most often to disable timeouts.

NNG_DURATION_ZERO

Zero length duration; used to perform a single polling operation.
