How to specify the domain for a man page

Question

I am trying to get man page for OpenSSL rsa. However when I type in man rsa I get the bash command rsa instead. How do I specify in the man command such that the OpenSSL RSA page will be displayed?

Answer 1

I think you want to see the man page of RSA_new, RSA_free function.

Please try

 man 3 rsa

You will get the man page of RSA functions and structure description.
