Hello,
Thanks for your answer. Here is one of d2i functions simplified:
MYEXT * d2i_MYEXT(MYEXT ** myext, unsigned char ** pp, long length) {
M_ASN1_D2I_vars(myext, MYEXT *, MYEXT_new);
M_ASN1_D2I_Init();
M_ASN1_D2I_start_sequence();
M_ASN1_D2I_get_EXP_opt(ret->intmember, d2i_ASN1_INTEGER, 1);
M_ASN1_D2I_get_opt(ret->intmember, d2i_ASN1_INTEGER, V_ASN1_INTEGER);
M_ASN1_D2I_Finish(myext, MYEXT_free, ASN1_F_D2I_MYEXT);
}
Regards,
A.K.
