[OpenCA-Devel] the document about code structure and API programing of openca PKI && how to develop PKI program using API

[Jordan S. <xin...@gm...>]

Dear OpenCA-developers,
Recently, I am studying the program of openca PKI and plan to develop a PKi-infrastructure using it. On the Official Website http://www.openca.org/projects/openca/ and google search, I have found only a few document such as openca-guide.pdf (no image) , which is related to some information about openca's use. Howerver, I can't find the information about code structure and API programing of openca PKI, so I'm confused how to develop PKI program using API.
Can anyone give me some documents or guidance about code structure and API programing of openca PKI? 
Thank you very much and I am greatly appreciated!
