Processes

Run child processes without blocking the other coroutines.

Introduction#

Process::run() (through ProcessRunner, behind ProcessInterface) starts a child process and hands back its standard streams to read and write from a coroutine, without blocking the others while it runs. See Running processes for starting several at once, talking back and forth, and timing one out.

Guides#

• Running processes – Run external programs without blocking a worker.

Examples#

• All examples of this topic – 3 with their output.

Reference#

• Process – Starts a child process whose standard streams are used from coroutines without blocking the others.
• ProcessInterface – A child process started with Process::run(), with its standard streams usable from coroutines.
• ProcessRunner – The implementation behind Process::run(): starts a child process and controls it.
