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 stdio-based file manipulation; the ov_fopen() and ov_open() calls internally provide default callbacks for -stdio. ov_callbacks are defined and passed to ov_open_callbacks() when -implementing non-stdio based stream manipulation (such as playback -from a memory buffer) or when ov_open()-style initialization from a FILE * is required under Windows [a]. -

Relevant Struct Members

read_func: Pointer to custom data reading function.
seek_func: Pointer to custom data seeking function. If the data source is not seekable (or the application wants the data source to be treated as unseekable at all times), the provided seek callback should always return -1 (failure) or the seek_func and tell_func fields should be set to NULL.
close_func: Pointer to custom data source closure function. Set to NULL if libvorbisfile should not attempt to automatically close the file/data handle.
tell_func: Pointer to custom data location function. If the data source is not seekable (or the application wants the data source to be treated as unseekable at all times), the provided tell callback should always return -1 (failure) or the seek_func and tell_func fields should be set to NULL.

Predefined callbacks

-The header vorbis/vorbisfile.h provides several predefined static ov_callbacks structures that may be passed to ov_open_callbacks(): -

OV_CALLBACKS_DEFAULT: - -These callbacks provide the same behavior as used internally by ov_fopen() and ov_open(). - -
OV_CALLBACKS_NOCLOSE: - -The same as OV_CALLBACKS_DEFAULT, but with the -close_func field set to NULL. The most typical use would be -to use ov_open_callbacks() to -provide the same behavior as ov_open(), but -not close the file/data handle in ov_clear(). - -
OV_CALLBACKS_STREAMONLY: - -A set of callbacks that set seek_func and tell_func -to NULL, thus forcing strict streaming-only behavior regardless of -whether or not the input is actually seekable. - -
OV_CALLBACKS_STREAMONLY_NOCLOSE: - -The same as OV_CALLBACKS_STREAMONLY, but with -close_func also set to null, preventing libvorbisfile from -attempting to close the file/data handle in ov_clear(). - -

- -

Examples and usage

- -See the callbacks and non-stdio I/O document for more -detailed information on required behavior of the various callback -functions.
