Types

type Table

type Table struct {
	InputFD      uintptr  // input file descriptor
	OutputFD     uintptr  // output file descriptor
	StatusFD     uintptr  // status file descriptor
	PassphraseFD uintptr  // passphrase file descriptor
	CommandFD    uintptr  // command file descriptor
	InputFP      *os.File // input file pointer
	OutputFP     *os.File // output file pointer
	StatusFP     *os.File // status file pointer
	PassphraseFP *os.File // passphrase file pointer
	CommandFP    *os.File // command file pointer
}

Table contains all standard file descriptors and file pointers.

func NewTable

func NewTable(c *cli.Context) (*Table, error)

NewTable parses the standard file descriptor options in context c and returns a table with the corresponding file descriptors and file pointers.
