Allocates a block of memory within the process, with size and access permissions specified in the arguments. The permissions argument is an or-combination of zero or more of lldb.ePermissionsWritable, lldb.ePermissionsReadable, and lldb.ePermissionsExecutable. Returns the address of the allocated buffer in the process, or lldb.LLDB_INVALID_ADDRESS if the allocation failed.

FixAddress(SBProcess self, lldb::addr_t addr, lldb::AddressMaskType type=eAddressMaskTypeAny) → lldb::addr_t

Given a virtual address, clear the bits that are not used for addressing (and may be used for metadata, memory tagging, point authentication, etc). By default the most general mask, lldb.eAddressMaskTypeAny is used to process the address, but lldb.eAddressMaskTypeData and lldb.eAddressMaskTypeCode may be specified if the type of address is known.

GetAddressMask(SBProcess self, lldb::AddressMaskType type, lldb::AddressMaskRange addr_range=eAddressMaskRangeLow) → lldb::addr_t

Get the current address mask in this Process of a given type. There are lldb.eAddressMaskTypeCode and lldb.eAddressMaskTypeData address masks, and on most Targets, the the Data address mask is more general because there are no alignment restrictions, as there can be with Code addresses. lldb.eAddressMaskTypeAny may be used to get the most general mask. The bits which are not used for addressing are set to 1 in the returned mask. In an unusual environment with different address masks for high and low memory, this may also be specified. This is uncommon, default is lldb.eAddressMaskRangeLow.

if error.Success():
    print('cstring: ', cstring)
else
    print('error: ', error)

ReadMemory(SBProcess self, lldb::addr_t addr, void * buf, SBError error) → size_t
