sox_format_t format, * ft = &format;
memset(ft, 0, sizeof(*ft));
ft->filename = (char *)device_name(name);
ft->priv = lsx_calloc(1, handler->priv_size);
if (handler->startwrite(ft) == SOX_SUCCESS) {
the format general (format_t) and specific (priv) structures are being zero'd so the \
handlers must be able to open the device using default parameters (sampling rate, \
number of channels etc.). If some don't then a fix could be needed in the handler or \
here to "fill in" some structure fields with non-zero values.
As I mentioned earlier to Pascal (but forgot to hit reply to all), I've committed \
this (but SourceForge's commit mail seemed to be broken) in the expectation that it \
will be tested before or during the next RC cycle.
Cheers,
Rob
