use $e = $con->sendRecv("command"); every time for each send you do you must do a recv so this does both. On Sat, Jan 30, 2010 at 8:48 AM, lakshmanan ganapathy <lakindia89@gmail.com>wrote:
Dear all
I've done the following sample script to experiment the nixevent. I found some difference in behavior because of nixevent. Let me explain my question down the script.
require ESL; use IO::Socket::INET;
my $ip = "192.168.1.222"; my $sock = new IO::Socket::INET ( LocalHost => $ip, LocalPort => '8447', Proto => 'tcp', Listen => 1, Reuse => 1 ); die "Could not create socket: $!\n" unless $sock; for(;;) { my $new_sock = $sock->accept(); next if (not defined ($new_sock)); my $pid = fork(); if ($pid) { close($new_sock); next; } print "CHILD PID: $$\n"; my $host = $new_sock->sockhost(); my $fd = fileno($new_sock);
my $con = new ESL::ESLconnection($fd); my $info = $con->getInfo();
my $uuid = $info->getHeader("unique-id");
printf "Connected call %s, from %s\n", $uuid, $info->getHeader("caller-caller-id-number"); my $r=$con->execute("answer"); $con->events("plain","all"); ########################## $con->send("nixevent DTMF"); my $val=$con->api("create_uuid"); $val = $val->getBody(); # LINE 1 chomp($val); print "UUID is $val\n"; my $e = $con->recvEvent(); $val = $e->getBody(); # LINE 2 chomp($val); print "UUID is $val\n"; close($new_sock); }
# If the line ($con->send("nixevent DTMF");) is commented, then the result of create_uuid is obtained in LINE 1. # else, the result isn't obtained in the LINE 1 and it has nothing. The result is obtained only when I do a recvEvent, # followed by a getBody (LINE 2)
Just want to know why the behavior differs when nixevent is present???
