How does one get the components of X509_NAME_ENTRY structure?

See more:

Windows

C++98

OpenSSL

The following code snippets are from OpenSSL websites.

//Process all entries.

int i;
 X509_NAME_ENTRY *e;

 for (i = 0; i < X509_NAME_entry_count(nm); i++)
        {
        e = X509_NAME_get_entry(nm, i);
        /* Do something with e */
        }

//Process all common names.
int loc;
 X509_NAME_ENTRY *e;

 loc = -1;
 for (;;)
        {
        lastpos = X509_NAME_get_index_by_NID(nm, NID_commonName, lastpos);
        if (lastpos == -1)
                break;
        e = X509_NAME_get_entry(nm, lastpos);
        /

I wish to get entries such as Common Name, Country, Organisation etc.

How do I get them from the X509-NAME-ENTRY structure that is returned from the code snippets above. Or is there a better way to go about getting the said entries?

I am yet to find any useful result from google search.
