static int	RTLD_DI_TLS_MODID() Treat ARG as `size_t *', and store there the TLS module ID of this object's PT_TLS segment, as used in TLS relocations; store zero if this object does not define a PT_TLS segment.
static int	RTLD_DL_LINKMAP() The object containing the address (struct link_map *).
static int	RTLD_DL_SYMENT() Matching symbol table entry (const ElfNN_Sym *).

Constructor Detail

LinuxDlfcn

public LinuxDlfcn()

Method Detail

RTLD_BINDING_MASK

public static int RTLD_BINDING_MASK()

Mask of binding time value.

RTLD_DEEPBIND

public static int RTLD_DEEPBIND()

Use deep binding.

LM_ID_BASE

public static int LM_ID_BASE()

Initial namespace.

LM_ID_NEWLM

public static int LM_ID_NEWLM()

For dlmopen: request new namespace.

dladdr1

public static int dladdr1(org.graalvm.word.PointerBase address,
                          Dlfcn.Dl_info info,
                          org.graalvm.word.PointerBase extra_info,
                          int flags)

Same as `dladdr', but additionally sets *EXTRA_INFO according to FLAGS.

RTLD_DL_SYMENT

public static int RTLD_DL_SYMENT()

Matching symbol table entry (const ElfNN_Sym *).

RTLD_DL_LINKMAP

public static int RTLD_DL_LINKMAP()

The object containing the address (struct link_map *).

dlinfo

public static int dlinfo(org.graalvm.word.PointerBase handle,
                         int request,
                         org.graalvm.word.PointerBase arg)

Get information about the shared object HANDLE refers to. REQUEST is from among the values below, and determines the use of ARG. On success, returns zero. On failure, returns -1 and records an error message to be fetched with `dlerror'.

RTLD_DI_LMID

public static int RTLD_DI_LMID()

Treat ARG as `lmid_t *'; store namespace ID for HANDLE there.

RTLD_DI_LINKMAP

public static int RTLD_DI_LINKMAP()

Treat ARG as `struct link_map **'; store the `struct link_map *' for HANDLE there.

RTLD_DI_CONFIGADDR

public static int RTLD_DI_CONFIGADDR()

Unsupported, defined by Solaris.

RTLD_DI_SERINFO

public static int RTLD_DI_SERINFO()

Treat ARG as `Dl_serinfo *' (see below), and fill in to describe the directories that will be searched for dependencies of this object. RTLD_DI_SERINFOSIZE fills in just the `dls_cnt' and `dls_size' entries to indicate the size of the buffer that must be passed to RTLD_DI_SERINFO to fill in the full information.

RTLD_DI_SERINFOSIZE

public static int RTLD_DI_SERINFOSIZE()

RTLD_DI_ORIGIN

public static int RTLD_DI_ORIGIN()

Treat ARG as `CCharPointer ', and store there the directory name used to expand $ORIGIN in this shared object's dependency file names.

RTLD_DI_PROFILENAME

public static int RTLD_DI_PROFILENAME()

Unsupported, defined by Solaris.

RTLD_DI_PROFILEOUT

public static int RTLD_DI_PROFILEOUT()

Unsupported, defined by Solaris.

RTLD_DI_TLS_MODID

public static int RTLD_DI_TLS_MODID()

Treat ARG as `size_t *', and store there the TLS module ID of this object's PT_TLS segment, as used in TLS relocations; store zero if this object does not define a PT_TLS segment.

RTLD_DI_TLS_DATA

public static int RTLD_DI_TLS_DATA()

Treat ARG as ` PointerBase *', and store there a pointer to the calling thread's TLS block corresponding to this object's PT_TLS segment. Store a null pointer if this object does not define a PT_TLS segment, or if the calling thread has not allocated a block for it.

RTLD_DI_MAX

public static int RTLD_DI_MAX()
