Hello
I'm using openssl as client in blocking mode , i have a problem .
Sometimes my program can't receive data , and acctually server has been sent the data to me.
I can only receive the data by sending another request . Then the data i expected arrived with a new data sent by server .
------------------------------------------------------------------------------
bool can_read()
{
if(SSL_pending(m_ssl))
return true;
struct timeval tv = {0 , 100};
FD_ZERO(&m_rfds);
FD_SET(m_socket.fd(), &m_rfds);
int ret = select( m_socket.fd()+1, &m_rfds , NULL, NULL, &tv);
return ret > 0 ;
}
//this is the main process
int try_receive(char * buf , int len )
{
if( !can_read())
return -1;
return SSL_read(m_ssl, buf, len);
}
-------------------------------------------------------------------------------
Above is my code , my program get `false` from `can_read` although the server has sent response data
I really appreciate your help.
