Functions

func GetDebugSectionElf added in v1.1.0 

func GetDebugSectionElf(f *elf.File, name string) ([]byte, error)

GetDebugSectionElf returns the data contents of the specified debug section, decompressing it if it is compressed. For example GetDebugSectionElf("line") will return the contents of .debug_line, if .debug_line doesn't exist it will try to return the decompressed contents of .zdebug_line.

func GetDebugSectionMacho(f *macho.File, name string) ([]byte, error)

GetDebugSectionMacho returns the data contents of the specified debug section, decompressing it if it is compressed. For example GetDebugSectionMacho("line") will return the contents of __debug_line, if __debug_line doesn't exist it will try to return the decompressed contents of __zdebug_line.

func GetDebugSectionPE added in v1.1.0 

func GetDebugSectionPE(f *pe.File, name string) ([]byte, error)

GetDebugSectionPE returns the data contents of the specified debug section, decompressing it if it is compressed. For example GetDebugSectionPE("line") will return the contents of .debug_line, if .debug_line doesn't exist it will try to return the decompressed contents of .zdebug_line.
