SDL_SeekIO — Seek within an SDL_IOStream
data stream.

Defined in SDL3/SDL_iostream.h

#include "SDL3/SDL.h"

Sint64 SDL_SeekIO(SDL_IOStream *context, Sint64 offset, SDL_IOWhence whence);

This function seeks to byte offset , relative to whence . whence may be any of the following values:

· SDL_IO_SEEK_SET : seek from the beginning of data

· SDL_IO_SEEK_CUR : seek relative to current read point

· SDL_IO_SEEK_END : seek relative to the end of data

If this stream can not seek, it will return -1.

context

a pointer to an SDL_IOStream
structure.

offset

an offset in bytes, relative to whence location; can be negative.

whence

any of SDL_IO_SEEK_SET , SDL_IO_SEEK_CUR , SDL_IO_SEEK_END .

( Sint64 ) Returns the final offset in the data stream after the seek or -1 on failure; call SDL_GetError () for more information.

This function is not thread safe.

This function is available since SDL 3.2.0.
