Hello, everyone !
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 .
Below is my code
------------------------------------------------------------------------------
bool can_read()
{
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);
}
-------------------------------------------------------------------------------
I'd really appreciate if you could tell me what's wrong with this code
