Add a new command to execute by the Async AGI application.
- Parameters:
-
s m It will append the application to the specified channel's queue if the channel is not inside Async AGI application it will return an error
- Return values:
-
0 on success or incorrect use 1 on failure to add the command ( most likely because the channel is not in Async AGI loop )

/* This buffer sizes might cause truncation if the AGI command writes more data
than AGI_BUF_SIZE as result. But let's be serious, is there an AGI command
that writes a response larger than 1024 bytes?, I don't think so, most of
them are just result=blah stuff. However probably if GET VARIABLE is called
and the variable has large amount of data, that could be a problem. We could
make this buffers dynamic, but let's leave that as a second step.
AMI_BUF_SIZE is twice AGI_BUF_SIZE just for the sake of choosing a safe
number. Some characters of AGI buf will be url encoded to be sent to manager
clients. An URL encoded character will take 3 bytes, but again, to cause
truncation more than about 70% of the AGI buffer should be URL encoded for
that to happen. Not likely at all.
On the other hand. I wonder if read() could eventually return less data than
the amount already available in the pipe? If so, how to deal with that?
So far, my tests on Linux have not had any problems.
