Use of Passphrase Callback

[SHARMA Sandhya (MORPHO)]

Hello,

I am Using gnupg on windows and want to use "Passphrase Callback" functionality to input password for private key.
My current lines of code is:
error = gpgme_set_pinentry_mode(context,GPGME_PINENTRY_MODE_LOOPBACK);
gpgme_passphrase_cb_t func = &passphrase_callback;
gpgme_pinentry_mode_t pinMode =  gpgme_get_pinentry_mode(context);
void *pp = 0;
gpgme_set_passphrase_cb(context,func,pp);

and declaration of gpgme_passphrase_cb_t is
gpgme_error_t passphrase_callback(void *opaque, const char *uid_hint, const char *desc,int prev_was_bad, int fd)

but breakpoint on this function never hits.
Kindly provide help on this or any example used to implement Passphrase CallBack.



Thanks & Regards,
Sandhya Sharma
