*n/a: platform not supported by Go *??: not tested

Go on plan9 and solaris do not implement syscall.Select nor syscall.SYS_SELECT.

Cross compile test

Note that this only tests the compilation, not the functionality.

Functions

func RetrySelect

func RetrySelect(n int, r, w, e *FDSet, timeout time.Duration, retries int, retryDelay time.Duration) (err error)

RetrySelect wraps syscall.Select with Go types, and retries a number of times, with a given retryDelay.

func Select

func Select(n int, r, w, e *FDSet, timeout time.Duration) error

Select wraps syscall.Select with Go types

Types

type FDSet

type FDSet syscall.FdSet

FDSet wraps syscall.FdSet with convenience methods

func (*FDSet) Clear

func (fds *FDSet) Clear(fd uintptr)

Clear remove the fd from the set

func (*FDSet) IsSet

func (fds *FDSet) IsSet(fd uintptr) bool

IsSet check if the given fd is set

func (*FDSet) Set

func (fds *FDSet) Set(fd uintptr)

Set adds the fd to the set

func (*FDSet) Zero

func (fds *FDSet) Zero()

Zero empties the Set
