ao_plugin_open

declared in "ao/plugin.h";

Open the device for playback. All of the device options will have already been set by previous calls to ao_plugin_set_option(). If this is a file output driver, the file itself will have be already opened and a pointer to a FILE structure stored in device->file.

int ao_plugin_open(ao_device *device, ao_sample_format *format);

Parameters

device

Pointer to pre-allocated device structure. The plugin should set its desired byte format in device->driver_byte_format.

format

Output device sample format. format->byte_format should be ignored as it is relevant only to the library core.

Return Values

1 indicates success.

0 indicates failure to open the device. ao_plugin_device_clear() should be called to ensure the deallocate of all private data structures.
