true if the ownership of the mutex has been acquired successfully, false otherwise. ExceptionsAny exceptions thrown by mutex()->try_lock_for(timeout_duration). If there is no associated mutex, std::system_error with an error code of std::errc::operation_not_permitted. ...

i cannot manage the paramters of contextGen like the ((scheme)) type, and ((t_bits)).. Also i cannot enter ((p value)) with 13 Digit Number the maximum is 9 digit number.. it gives me an error from 10 digits and up, is that normal? or this is a package problem? How can ...
Therefore it is especially useful as an object with automatic duration, as it guarantees the mutex object is properly unlocked in case an exception is thrown. Note though, that the unique_lock object does not manage the lifetime of the mutex object in any way: the duration of the mutex ...

std::unique_lock Defined in header<mutex> template<classMutex> classunique_lock; (since C++11) The classunique_lockis a general-purpose mutex ownership wrapper allowing deferred locking, time-constrained attempts at locking, recursive locking, transfer of lock ownership, and use with condition varia...
