Bug #6343 ยป Added-documentation-for-fiber-transfer.patch
| cont.c | ||
|---|---|---|
|
* You cannot resume a fiber that transferred control to another one.
|
||
|
* This will cause a double resume error. You need to transfer control
|
||
|
* back to this fiber before it can yield and resume.
|
||
|
*
|
||
|
* Example:
|
||
|
*
|
||
|
* fiber1 = Fiber.new do
|
||
|
* puts "In Fiber 1"
|
||
|
* Fiber.yield
|
||
|
* end
|
||
|
*
|
||
|
* fiber2 = Fiber.new do
|
||
|
* puts "In Fiber 2"
|
||
|
* fiber1.transfer
|
||
|
* end
|
||
|
*
|
||
|
* fiber3 = Fiber.new do
|
||
|
* puts "In Fiber 3"
|
||
|
* end
|
||
|
*
|
||
|
* fiber2.resume
|
||
|
* fiber3.resume
|
||
|
*
|
||
|
* <em>produces</em>
|
||
|
*
|
||
|
* I am in fiber2
|
||
|
* I am in fiber1
|
||
|
* I am in fiber3
