Hi Matt,
Thanks for the reply.. we would implement as you suggested.

If I understand correctly you want to store an "int" value internally to
a custom BIO.
Custom BIOs can associate an arbitrary data structure with the BIO
object and store whatever they like in it using the BIO_get_data() and
BIO_set_data() functions.
For example:
typedef struct {
int num;
} XYZ_PRIVATE_DATA;
static int XYZ_mem_new(BIO *bio)
{
XYZ_PRIVATE_DATA *data = OPENSSL_zalloc(sizeof(*data));
if (data == NULL)
return 0;
/* Store whatever you like in num */
data->num = 5;
BIO_set_data(bio, data);
}
static int XYZ_mem_free(BIO *bio)
{
XYZ_PRIVATE_DATA *data = BIO_get_data(bio);
OPENSSL_free(data);
BIO_set_data(bio, NULL);
}
static int XYZ_mem_read(BIO *bio, char *out, int outl)
{
XYZ_PRIVATE_DATA *data = BIO_get_data(bio);
/* Do the read operation and use data->num as required */
}

Re: set/get utilities are not available to access variable 'num' of structure bio_st (Matt Caswell)
Hi Matt, We are using MEM type BIO. similar to the openssl library ‘BIO_TYPE_MEM ‘ we have an internal type defined like ex:- ‘BIO_TYPE_XYZ_MEM’ and all other mem utilities are internally defined. Like XYZ_mem_new/XYZ_mem_read … etc these utilities are accessing the bio_st variable ‘num’. please suggest set/get utilities to handle this scenario.
