Functions ¶

func Close ¶

func Close(fd int) error

func FileStatToUnixMode ¶

func FileStatToUnixMode(fsMode os.FileMode) uint32

func Fstat ¶

func Fstat(fd int, stat *Stat_t) error

func Fstatat ¶

func Makedev ¶

func Makedev(major, minor uint64) (uint64, error)

Supports basic makedev implementation. Most kernels support major/minors larger than 255 however how this is encoded varies between kernels therefore we only support 8 bit major/minors which is consistently represented.

func Read ¶

func Read(fd int, p []byte) (int, error)

func Readlinkat ¶

func Readlinkat(dirfd int, path string, buf []byte) (int, error)

func RetrySyscall6 ¶

func RetrySyscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (uintptr, uintptr, error)

Invoke a syscall that returns an int and an error, retrying on EINTR

func RetrySyscallE ¶

func RetrySyscallE(callSyscallE func() error) error
