type File ¶
- type File struct {
- FileHeader
- Sections []*Section
- // contains filtered or unexported fields
- }
A File represents an open Plan 9 a.out file.
func NewFile ¶
NewFile creates a new File for accessing a Plan 9 binary in an underlying reader. The Plan 9 binary is expected to start at position 0 in the ReaderAt.
func Open ¶
Open opens the named file using os.Open and prepares it for use as a Plan 9 a.out binary.
func (*File) Close ¶
Close closes the File. If the File was created using NewFile directly instead of Open, Close has no effect.
func (*File) Section ¶
Section returns a section with the given name, or nil if no such section exists.
func (*File) Symbols ¶
Symbols returns the symbol table for f.
type FileHeader ¶
A FileHeader represents a Plan 9 a.out file header.
type Section ¶
- type Section struct {
- SectionHeader
- // Embed ReaderAt for ReadAt method.
- // Do not embed SectionReader directly
- // to avoid having Read and Seek.
- // If a client wants Read and Seek it must use
- // Open() to avoid fighting over the seek offset
- // with other clients.
- io.ReaderAt
- // contains filtered or unexported fields
- }
A Section represents a single section in a Plan 9 a.out file.
func (*Section) Data ¶
Data reads and returns the contents of the Plan 9 a.out section.
func (*Section) Open ¶
- func (s *Section) Open() io.ReadSeeker
Open returns a new ReadSeeker reading the Plan 9 a.out section.
type SectionHeader ¶
A SectionHeader represents a single Plan 9 a.out section header. This structure doesn’t exist on-disk, but eases navigation through the object file.
type Sym ¶
A Symbol represents an entry in a Plan 9 a.out symbol table section.
