command line to c++ code

[luis hernandez]

Hi 
I do not know if you have talk about this here, but I can not find the answer.
 
How to translate a command line commandt to a c++ code?
 
For instance if at commandd prompt i do this: openssl x509 -inform DER -in 
cert.cer -noout -enddate
 
What code will generate the same result?
 
Is there howto already written?
 
I have bought the book Network security with Openssl by O'reilly. But I can not 
figure it out.
 
TIA for your help.
