POSIX defines signal.h. sys/signal.h should not be used as it is c-library internal header which may or may not exist. Notably with musl it generates warning of being incorrect. Change-Id: Ia56b0aa1d84b5c590114867b1b384a624f39a6fc

|
|
* To install portaudio v19 from svn, check it out using the following command:
|
|
* - svn co https://www.portaudio.com/repos/portaudio/branches/v19-devel
|
|
*
|
|
* \note Since this works with any audio system that libportaudio supports,
|
|
* including ALSA and OSS, this may someday deprecate chan_alsa and chan_oss.
|
|
* However, before that can be done, it needs to *at least* have all of the
|
|
* features that these other channel drivers have. The features implemented
|
|
* in at least one of the other console channel drivers that are not yet
|
|
* implemented here are:
|
|
*
|
|
* - Set Auto-answer from the dialplan
|
|
* - transfer CLI command
|
|
* - boost CLI command and .conf option
|
|
* - console_video support

/*
|
|
* \brief Implementation of the ast_channel_tech read() callback
|
|
*
|
|
* Calling this function is harmless. However, if it does get called, it
|
|
* is an indication that something weird happened that really shouldn't
|
|
* have and is worth looking into.
|
|
*
|
|
* Why should this function not get called? Well, let me explain. There are
|
|
* a couple of ways to pass on audio that has come from this channel. The way
|
|
* that this channel driver uses is that once the audio is available, it is
|
|
* wrapped in an ast_frame and queued onto the channel using ast_queue_frame().
|
|
*
|
|
* The other method would be signalling to the core that there is audio waiting,
|
|
* and that it needs to call the channel's read() callback to get it. The way
|
|
* the channel gets signalled is that one or more file descriptors are placed
|
|
* in the fds array on the ast_channel which the core will poll() on. When the
|
|
* fd indicates that input is available, the read() callback is called. This
|
|
* is especially useful when there is a dedicated file descriptor where the
|
|
* audio is read from. An example would be the socket for an RTP stream.
