"Represents an executable image and its associated object and symbol files.
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:
