Post Does recursive mutex lock in openssl will affect other openssl users in same system?


I need a clarification in below problem.

Problem:
I am writing a wrapper to use openssl in which I am locking (mutex) and adding certificate information to openssl store using X509_STORE_add_cert() function and also doing some more steps followed by this.

Here my problem is, to update openssl store, I have locked the whole operation before calling X509_STORE_add_cert() and with in this function once again the same lock is used to actually update the openssl store. So, I have used "pthread_mutex_recursive" attribute for mutex and my code works fine.

But, since I am initializing array of global mutex list with "pthread_mutex_recursive", will it affect the other openssl clients in the system?

Kindly reply and help me in this regard.
Thanks in advance.

A mutex defined in one process is unrelated to a mutex in another process.

Hi,

Thanks for your information.
But, sorry for asking the same kind of question in this regard.

Since I am making all the mutexs to recursive lock (because I will get mutex number to lock during run time), will that affect other threads/processes which uses OpenSSL where those other threads/processes might not need the recursive mutex?

Thanks in advance.
