As Jim said, we have many different kinds of breakpoints and breakpoints can
have N SBBreakpointLocations and that number can change as your process runs
and more shared libraries are loaded.
If you set a source file and line breakpoint to begin with, then iterating over
the locations is the best way to see what you ended up with.
bp = target.BreakpointCreateByLocation("/tmp/main.cpp", 12)
for bp_loc in bp:
addr = bp_loc.GetAddress()
line_entry = addr.GetLineEntry()
file_spec = line_entry.GetFileSpec()
line = line_entry.GetLine()
column = line_entry.GetColumn()
If you just want the breakpoint source file, line and column as a string value,
just run str() on the line_entry:
>>> bp = lldb.target.BreakpointCreateByLocation("main.cpp", 6)
>>> for l in bp:
... print(l.GetAddress().GetLineEntry())
...
/Users/gclayton/Documents/src/args/main.cpp:6:14
It will print everything out for you into a single string. Note the print()
statement above calls str() on "l.GetAddress().GetLineEntry()" for you.
