== DESCRIPTION
|
|
|
|
An `nng_duration`(((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.
