◆ rb_fiber_scheduler_io_result()

static VALUE rb_fiber_scheduler_io_result	(	ssize_t	result,
		int	error
	)

inlinestatic

Wrap a ssize_t and int errno into a single VALUE.

This interface should be used to safely capture results from system calls like read and write.

You should use rb_fiber_scheduler_io_result_apply to unpack the result of this value and update int errno.

You should not directly try to interpret the result value as it is considered an opaque representation. However, the general representation is an integer in the range of [-int errno, size_t size]. Linux generally restricts the result of system calls like read and write to <= 2^31 which means this will typically fit within a single FIXNUM.

Parameters

[in]	result	The result of the system call.
[in]	error	The value of `errno`.

Returns: A VALUE which contains the result and/or errno.

Definition at line 48 of file scheduler.h.

◆ rb_fiber_scheduler_io_result_apply()

static ssize_t rb_fiber_scheduler_io_result_apply ( VALUE result )

inlinestatic

Apply an io result to the local thread, returning the value of the original system call that created it and updating int errno.

You should not directly try to interpret the result value as it is considered an opaque representation.

Parameters

[in] result The VALUE which contains an errno and/or result size.

Postcondition: Updates int errno with the value if negative.

Returns: The original result of the system call.

Definition at line 70 of file scheduler.h.

◆ rb_fiber_scheduler_io_select()

VALUE rb_fiber_scheduler_io_select	(	VALUE	scheduler,
		VALUE	readables,
		VALUE	writables,
		VALUE	exceptables,
		VALUE	timeout
	)

Non-blocking version of IO.select.

It's possible that this will be emulated using a thread, so you should not rely on it for high performance.

Parameters

[in]	scheduler	Target scheduler.
[in]	readables	An array of readable objects.
[in]	writables	An array of writable objects.
[in]	exceptables	An array of objects that might encounter exceptional conditions.
[in]	timeout	Numeric timeout or nil.

Returns: What scheduler.io_select returns, normally a 3-tuple of arrays of ready objects.

Definition at line 463 of file scheduler.c.

◆ rb_fiber_scheduler_io_selectv()

VALUE rb_fiber_scheduler_io_selectv	(	VALUE	scheduler,

Its implementation is up to the user.
