Instead of modifying the BIO, I've also tried to set it's socket to

BIO_socket_nbio(BIO_get_fd(pBio,NULL), 1);
BIO_do_connect(pBio); //returns -1

Sorry for typo, should be pBio instead of m_pBio everywhere.

And if you do this:
while(1) {
int rv = BIO_do_connect(m_pBio);
if(rv < 0) {
// Fix this line below with correct detection for a fatal or
non-fatal error, if BIO_do_connect() returns a fatal error we want to
abort, if BIO_do_connect() returns an expected non-fatal error we need
to delay and try again.
if(errno != EINPROGRESS)
break; // fatal error
// wait a bit and try again
sleep(1);
}
}
I am not familiar with BIO and nonbocking connects but the the connect()
system call will return -1/EINPROGRESS when the connect is not yet
connected but still working on establishing a connection.
Just a thought for you.
