func Big5ToUtf8(big5 []byte) (utf8 string)

func BinRead 

func BinRead(file io.ReadSeeker, v interface{}, theSize uintptr) error

BinRead

func BinWrite 

func BinWrite(file io.Writer, v interface{}, theSize uintptr) error

BinWrite

Write the file with identified size, the first bytes are with v. Assuming that the size of v is <= theSize. XXX not sure what to do if v > theSize.

func ReadLine(reader *bufio.Reader) ([]byte, error)

ReadLine

To avoid confusion, use only []byte is nil or not to know whether it's the end of file.

Types

type Cstr 

type Cstr []byte

Cstr

[]byte with C String property in that \0 is considered as the end of the bytes/string. It is used to convert from fixed-length bytes to string or []byte with no \0.

Naming Cstr instead of CString is to avoid confusion with C.CString (C.CString is from string, and should be compatible with string, not with []byte) (We also have str(len/cpy/cmp) functions in C)

See tests for more examples of how to use fixed-bytes with Cstr to get no-\0 string / []byte

func CstrTokenR added in v0.8.3

	Rune   rune  // unicode
}
