I know this doesn't have anything to do with the problem you are
facing, or with openssl for that matter (I'm afraid I can't help with
that), but isn't %m exclusive to the syslog() call? Does it also work
with printf() ?

Hi All,
I'm trying to decode a base64 encoded string. The problem I'm
running in to is that BIO_read() always returns 0.
BIO_should_retry() and BIO_should_read() also return 0 when
BIO_read() returns 0. If the base64 encoded string is shortened,
BIO_read returns the decoded information. I get this result using
OpenSSL 0.9.8k (cross-compiled for a Blackfin processor) and OpenSSL
0.9.8g on Ubuntu 9.04.
Any suggestions on what I'm doing wrong?
Thanks,
...doug
