Detailed Description
Default structure for translators, with the basic fields and buffers, all allocated as part of the same chunk of memory. The buffer is preceded by AST_FRIENDLY_OFFSET bytes in front of the user portion. 'buf' points right after this space.
*_framein() routines operate in two ways: 1. some convert on the fly and place the data directly in outbuf; in this case 'samples' and 'datalen' contain the number of samples and number of bytes available in the buffer. In this case we can use a generic *_frameout() routine that simply takes whatever is there and places it into the output frame. 2. others simply store the (unconverted) samples into a working buffer, and leave the conversion task to *_frameout(). In this case, the intermediate buffer must be in the private descriptor, 'datalen' is left to 0, while 'samples' is still updated with the number of samples received.
