ao_device

declared in "ao/ao.h";

This structure holds all of the data for an open device.

typedef struct {
  int  type; /* live output or file output? */
  int  driver_id;
  ao_functions *funcs;
  FILE *file; /* File for output if this is a file driver */
  int  client_byte_format;
  int  machine_byte_format;
  int  driver_byte_format;
  char *swap_buffer;
  int  swap_buffer_size; /* Bytes allocated to swap_buffer */
  void *internal; /* Pointer to driver-specific data */
} ao_device;

Relevant Struct Members

type
The output type of the driver:
driver_id
The ID number for the driver used with this device.
funcs
Function table for the driver associated with this device.
client_byte_format
The byte format (use constants from ao_sample_format) of samples provided by the client to ao_play().
machine_byte_format
The native byte format of the computer. Will be either AO_FMT_BIG or AO_FMT_LITTLE.
driver_byte_format
The byte format of samples requested by the driver.
swap_buffer
Scratch buffer used to swap the byte order of samples. Only allocated if client_byte_format and driver_byte_format correspond to different byte orders, otherwise set to NULL
