Modern Chan Channel ReceiveFor

Home › Goroutines and Channels › Goroutines and Channels › ReceiveFor

ReceiveFor

Receives a value, waiting at most ms milliseconds; false on a timeout or end of stream.

Syntax

ReceiveFor( byref out as T, byval ms as uint32 ) as boolean

Notes

• FALSE means the timeout expired or the channel is closed and drained.
• The output is left alone on a timeout.
• The receive-side counterpart of SendFor, and the shape a worker uses so it can check for cancellation between attempts.

Examples

#import "std/tasks"
using tasks

dim ch as Channel( of int32 ) = Channel( of int32 )( 1 )

dim as int32 got
print ch.ReceiveFor( got, 50 )       '' false -- nothing arrived in 50 ms

dim as int32 v = 7
ch.Send( v )
print ch.ReceiveFor( got, 100 )      '' true
print got                            '' 7
