Rose::BinaryAnalysis::BinaryLoaderElf::VersionedSymbol Class Reference

Description

Symbol from .dynsym combined with additional information.

The additional information is:

• The symbol's entry in the GNU Symbol Version Table (.gnu.version section)
• The symbol's entry in the GNU Symbol Version Definition Table (.gnu.version_d section), if any.
• The symbol's auxiliary information (and thus, indirectly, the table entry) from the GNU Symbol Version Requirements Table (.gnu.version_r section), if any.

bool Rose::BinaryAnalysis::BinaryLoaderElf::VersionedSymbol::isLocal

(

)

const

Returns true if this symbol is visible only locally.

bool Rose::BinaryAnalysis::BinaryLoaderElf::VersionedSymbol::isHidden

(

)

const
