The module is designed to be able to select a single slice of an executable image as it would appear on disk and during program execution. You can retrieve SBModule from SBSymbolContext, which in turn is available from SBFrame. SBModule supports symbol iteration, for example, for symbol in module: name = symbol.GetName() saddr = symbol.GetStartAddress() eaddr = symbol.GetEndAddress() and rich comparion methods which allow the API program to use, if thisModule == thatModule: print 'This module is the same as that module' to test module equality. A module also contains object file sections, namely SBSection. SBModule supports section iteration through section_iter(), for example, print 'Number of sections: %d' % module.GetNumSections() for sec in module.section_iter(): print sec And to iterate the symbols within a SBSection, use symbol_in_section_iter(), # Iterates the text section and prints each symbols within each sub-section. for subsec in text_sec: print INDENT + repr(subsec) for sym in exe_module.symbol_in_section_iter(subsec): print INDENT2 + repr(sym) print INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType()) produces this following output: [0x0000000100001780-0x0000000100001d5c) a.out.__TEXT.__text id = {0x00000004}, name = 'mask_access(MaskAction, unsigned int)', range = [0x00000001000017c0-0x0000000100001870) symbol type: code id = {0x00000008}, name = 'thread_func(void*)', range = [0x0000000100001870-0x00000001000019b0) symbol type: code id = {0x0000000c}, name = 'main', range = [0x00000001000019b0-0x0000000100001d5c) symbol type: code id = {0x00000023}, name = 'start', address = 0x0000000100001780 symbol type: code [0x0000000100001d5c-0x0000000100001da4) a.out.__TEXT.__stubs id = {0x00000024}, name = '__stack_chk_fail', range = [0x0000000100001d5c-0x0000000100001d62) symbol type: trampoline id = {0x00000028}, name = 'exit', range = [0x0000000100001d62-0x0000000100001d68) symbol type: trampoline id = {0x00000029}, name = 'fflush', range = [0x0000000100001d68-0x0000000100001d6e) symbol type: trampoline id = {0x0000002a}, name = 'fgets', range = [0x0000000100001d6e-0x0000000100001d74) symbol type: trampoline id = {0x0000002b}, name = 'printf', range = [0x0000000100001d74-0x0000000100001d7a) symbol type: trampoline id = {0x0000002c}, name = 'pthread_create', range = [0x0000000100001d7a-0x0000000100001d80) symbol type: trampoline id = {0x0000002d}, name = 'pthread_join', range = [0x0000000100001d80-0x0000000100001d86) symbol type: trampoline id = {0x0000002e}, name = 'pthread_mutex_lock', range = [0x0000000100001d86-0x0000000100001d8c) symbol type: trampoline id = {0x0000002f}, name = 'pthread_mutex_unlock', range = [0x0000000100001d8c-0x0000000100001d92) symbol type: trampoline id = {0x00000030}, name = 'rand', range = [0x0000000100001d92-0x0000000100001d98) symbol type: trampoline id = {0x00000031}, name = 'strtoul', range = [0x0000000100001d98-0x0000000100001d9e) symbol type: trampoline id = {0x00000032}, name = 'usleep', range = [0x0000000100001d9e-0x0000000100001da4) symbol type: trampoline [0x0000000100001da4-0x0000000100001e2c) a.out.__TEXT.__stub_helper [0x0000000100001e2c-0x0000000100001f10) a.out.__TEXT.__cstring [0x0000000100001f10-0x0000000100001f68) a.out.__TEXT.__unwind_info [0x0000000100001f68-0x0000000100001ff8) a.out.__TEXT.__eh_frame " ) SBModule; class SBModule { public: SBModule (); SBModule (const lldb::SBModule &rhs); SBModule (const lldb::SBModuleSpec &module_spec); SBModule (lldb::SBProcess &process, lldb::addr_t header_addr); ~SBModule (); bool IsValid () const; void Clear(); %feature("docstring", " //------------------------------------------------------------------ /// Get const accessor for the module file specification. /// /// This function returns the file for the module on the host system /// that is running LLDB.
