ov_callbacks

declared in "vorbis/codec.h"

The ov_callbacks structure contains file manipulation function prototypes necessary for opening, closing, seeking, and location.

The ov_callbacks structure does not need to be user-defined if you are working with a standard file. The typical ov_open() call will fill ov_callbacks for you. However, ov_callbacks should be defined if you are using other data sources. In this situation, use ov_open_callbacks() instead of ov_open().

typedef struct { size_t (*read_func) (void *ptr, size_t size, size_t nmemb, void *datasource); int (*seek_func) (void *datasource, int64_t offset, int whence); int (*close_func) (void *datasource); long (*tell_func) (void *datasource); } ov_callbacks;
