Hi all,
Firstly, happy new year & best wished to all.
I'm working on an application connecting to FTP server using ecos
ftpclient package. I constate that the application waits for ever on a
blocking semaphore of cyg_tsleep() function when there is no ftp server
available.
In fact, for connecting to ftp server, ftpclient uses connect() that
calls itself bas_connect() in which the while loop is used for waiting
for the connection etablishment or an error occurring :
while ((so->so_state & SS_ISCONNECTING) && so->so_error == 0) {
error = tsleep((caddr_t)&so->so_timeo, PSOCK | PCATCH,
netcon, 0);
if (error)
break;
}
The paramter timo of tsleep set to 0 makes cyg_tsleep waiting for a
blocking semaphore at line 325 of the file synch.c
(net/tcpip/current/src/ecos/synch.c). And the wait time is usually long
and triggers the watchdog process in my application.
I would like to know that there is any way to set up a timeout on socket
before calling connect() so that the application will be able to get out
this blocking situation ?
Any idea or sugestion will be appreciated.
Thank in advance for your helps.
