For what I understood recently (I had to work a bit with it), the macro
IMPLEMENT_ASN1_FUNCTIONS will expand (macro usage is quite heavy in
OpenSSL) to provide a number of functions for the struct KDC_PRINCNAME,
such as KDC_PRINCNAME_i2d, KDC_PRINCNAME_d2i, etc.
The magic works so that you do not have to implement those functions
with new code because the macros will expand the sequence (so that they
know what shal be done) and write the code for you.

Hi All,
I found a code snippet as follows:
ASN1_SEQUENCE(KDC_PRINCNAME) = {
ASN1_EXP(KDC_PRINCNAME, realm, ASN1_GENERALSTRING, 0),
ASN1_EXP(KDC_PRINCNAME, princname, KRB5_PRINCNAME, 1)
} ASN1_SEQUENCE_END(KDC_PRINCNAME);
IMPLEMENT_ASN1_FUNCTIONS(KDC_PRINCNAME)
Here ASN1_SEQUENCE implements the asn1 sequence of KDC_PRINCNAME, but
what is the functionality of
"IMPLEMENT_ASN1_FUNCTIONS(KDC_PRINCNAME)"? Is it compulsory to
include this function after defining every ASN1_SEQUENCE? Please
guide me.
Regards,
Vinay
