def get_stopped_threads(process, reason):
    '''Returns the thread(s) with the specified stop reason in a list.

    The list can be empty if no such thread exists.
    '''
    threads = []

Reads a pointer from memory from an address and returns the value. Example:

# Read a pointer from address 0x1000
error = lldb.SBError()
ptr = ReadPointerFromMemory(0x1000, error)
if error.Success():

ReadUnsignedFromMemory(addr: lldb::addr_t, byte_size: uint32_t, error: SBError) → uint64_t¶

Reads an unsigned integer from memory given a byte size and an address. Returns the unsigned integer that was read. Example:

# Read a 4 byte unsigned integer from address 0x1000
error = lldb.SBError()

WriteMemory(addr: lldb::addr_t, buf: void const *, error: SBError) → size_t¶

Writes memory to the current process’s address space and maintains any traps that might be present due to software breakpoints. Example:

# Create a Python string from the byte array.
new_value = str(bytes)
result = process.WriteMemory(addr, new_value, error)
if not error.Success() or result != len(bytes):
    print('SBProcess.WriteMemory() failed!')

WriteMemoryAsCString(addr, str, error)¶

WriteMemoryAsCString(self, addr, str, error):: This functions the same as WriteMemory except a null-terminator is appended to the end of the buffer if it is not there already.

get_process_thread_list()¶: An accessor function that returns a list() that contains all threads in a lldb.SBProcess object.

get_threads_access_object()¶: An accessor function that returns a modules_access() object which allows lazy thread access from a lldb.SBProcess object.
