remove_aux_requirement() [1/2]

bool LIEF::ELF::SymbolVersionRequirement::remove_aux_requirement ( const std::string & name )

inline

Try to remove the auxiliary requirement symbol with the given name. The function returns true if the operation succeed, false otherwise.

Warning

this function invalidates all the references (pointers) of SymbolVersionAuxRequirement. Therefore, the user is responsible to ensure that the auxiliary requirement is no longer used in the ELF binary (e.g. in SymbolVersion)
