Detailed Description

The callbacks used to access non-FILE stream resources.

The function prototypes are basically the same as for the stdio functions fread(), fseek(), ftell(), and fclose(). The differences are that the FILE * arguments have been replaced with a void *, which is to be used as a pointer to whatever internal data these functions might need, that seek and tell take and return 64-bit offsets, and that seek must return -1 if the stream is unseekable.

Field Documentation

op_read_func OpusFileCallbacks::read

Used to read data from the stream.

This must not be NULL.

op_seek_func OpusFileCallbacks::seek

Used to seek in the stream.

This may be NULL if seeking is not implemented.

op_tell_func OpusFileCallbacks::tell

Used to return the current read position in the stream.

This may be NULL if seeking is not implemented.

op_close_func OpusFileCallbacks::close

Used to close the stream when the decoder is freed.

This may be NULL to leave the stream open.
