you can use these functions to convert the RSA structure into an asn1-der string array(i2d_xxx) and use d2i_xxx to convert an asn1-der string array to RSA structure. you can see the Openssl Doc for more details of these functions.

I need to store it into a buffer for internal processing. Can you please suggest me to convert RSA a key into buffer. I had seen the examples to dump into file. Instead of file processing I need to convert RSA private key into buffer. Thanks Muneeswaran.R
