Parameters

callback	function to use as main loop for the newly-created fiber
stackSize	size of the stack to allocate for this fiber.

Returns: a newly-created fiber context.

Here is the call graph for this function:

struct Fiber * ns3::PthreadFiberManager::CreateFromCaller ( void )

readvirtual

Returns: an empty context

Create a fiber context which can be used as a from argument to the SwitchTo method This method is usually used to create a context which references the main 'normal' thread. i.e., the thread initially managed by the underlying kernel which runs on the kernel-managed stack.

Parameters

context to delete

Here is the caller graph for this function:

void ns3::PthreadFiberManager::SwitchTo	(	struct Fiber *	from,
		const struct Fiber *	to

virtual

Parameters

from	from context
to	to context

This function saves the caller's context into the from context and restores the current context from the to context. The first time this function is called, it is usually called with a from set to a context obtained through CreateFromCaller and with a to set to a context obtained through Create.
