Forward declaration; defined below.
Public Methods
void ~RuntimeModule ()See unmap-[posix|zircon].cc for the dtor. On destruction, the module's load
image is unmapped per the semantics of the OS implementation.
Defined at line 11 of file ../../sdk/lib/c/dlfcn/dl/unmap-zircon.cc
bool ReifyModuleTree (Diagnostics & diag)Constructs this module's `module_tree` if it has not been set yet.
Defined at line 14 of file ../../sdk/lib/c/dlfcn/dl/runtime-module.cc
void InitializeModuleTree ()Run the init functions for this module (as the root module) and the init
functions for all its dependencies.
Defined at line 50 of file ../../sdk/lib/c/dlfcn/dl/runtime-module.cc
void Initialize ()Run only this module's init functions. This is called if this module is
loaded as a dependency to another module.
Defined at line 63 of file ../../sdk/lib/c/dlfcn/dl/runtime-module.cc
void RuntimeModule (const RuntimeModule & )Not copyable, but movable.
Defined at line 74 of file ../../sdk/lib/c/dlfcn/dl/test/../runtime-module.h
void RuntimeModule (RuntimeModule && )Defined at line 75 of file ../../sdk/lib/c/dlfcn/dl/test/../runtime-module.h
bool operator== (const Soname & other)The name of the runtime module is set to the filename passed to dlopen() to
create the runtime module. This is usually the same as the DT_SONAME of the
AbiModule, but that is not guaranteed. When performing an equality check,
match against both possible name values.

const Soname & name ()Defined at line 89 of file ../../sdk/lib/c/dlfcn/dl/test/../runtime-module.h
const RuntimeModule & FromPtr (const void * ptr)Translate a void * pointer, as when passed to public-facing
<dlfcn
.h> APIs,
into a RuntimeModule reference.

void SetStartupModule (const AbiModule & abi_module, const ld::abi::Abi<> & abi)This is called if the RuntimeModule is created from a startup module (i.e.
a module that was linked and loaded with the running program). This sets
the abi, TLS, and direct_deps information onto the RuntimeModule.

const SymbolInfo & symbol_info ()The following methods satisfy the Module template API for use with
elfldltl::ResolverDefinition (see
<lib
/elfldltl/resolve.h>).

const ld::abi::Abi<>::LinkMap & link_map ()Defined at line 152 of file ../../sdk/lib/c/dlfcn/dl/test/../runtime-module.h
const struct link_map * user_link_map ()The ld::abi::Abi
<
>::LinkMap embedded in the RuntimeModule's ABI module is
compatible with `struct link_map` (see
<lib
/elfldltl/svr4-abi.h>). This
will cast the module's LinkMap into the `struct link_map` type used by
users of the public-facing
<dlfcn
.h> API.

Vector<RuntimeModule *> & direct_deps ()This is a list of module pointers to this module's DT_NEEDEDs, i.e. the
first level of dependencies in this module's module tree. If this list is
empty, the module does not have any dependencies.

this module's tree of modules. A reference to this module (the root) is
always the first in this list. The other modules in this list are
non-owning references to modules that were explicitly linked with this
module; global modules that may have been used for relocations, but are
not a DT_NEEDED of any dependency, are not included in this list. This
list is set when dlopen() is called on this module.

bool is_global ()Whether this module is a global module: either the module was loaded at
startup or loaded by dlopen() with the RTLD_GLOBAL flag.

bool is_local ()Defined at line 205 of file ../../sdk/lib/c/dlfcn/dl/test/../runtime-module.h
void set_no_delete ()Prevent this module from being unloaded. Once this is set (usually by
passing RTLD_NODELETE to dlopen), it cannot be unset. Setting this on a
module implies that none of its dependencies can be unloaded either: since
this module will live for the lifetime of the main program, so will its
dependencies.

TlsdescIndirectList & tls_desc_indirect_list ()This is the list of TlsDesc objects (see tls-desc-resolver.h) that was set
during TLS relocation for this module. The RuntimeModule owns this list:
it will get destroyed with the module.

dl_phdr_info MakeDlPhdrInfo (void * tls_data, ld::DlPhdrInfoCounts counts)Construct the `dl_phdr_info` for this module.
