Presumably the two fields aren't the same? I'll call one intmember2 for
this example.
The above would translate to something like:
ASN1_SEQUENCE(MYEXT) = {
ASN1_EXP_OPT(MYEXT, intmember, ASN1_INTEGER, 1),
ASN1_OPT(MYEXT, intmember2, ASN1_INTEGER)
} ASN1_SEQUENCE_END(MYEXT)
IMPLEMENT_ASN1_FUNCTIONS(MYEXT)
Then you include:
DECLARE_ASN1_FUNCTIONS(MYEXT)
in a header file.
That generates four functions MYEXT_new(), MYEXT_free(), d2i_MYEXT() and
i2d_MYEXT().
