Seek within an SDL_IOStream data stream.
Defined in <SDL3/SDL_iostream.h>
Sint64 SDL_SeekIO(SDL_IOStream *context, Sint64 offset, SDL_IOWhence whence);| SDL_IOStream * | context | a pointer to an SDL_IOStream structure. |
| Sint64 | offset | an offset in bytes, relative to whence location; can be
negative. |
| SDL_IOWhence | 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 seeks to byte offset, relative to
whence.
whence may be any of the following values:
SDL_IO_SEEK_SET:
seek from the beginning of dataSDL_IO_SEEK_CUR:
seek relative to current read pointSDL_IO_SEEK_END:
seek relative to the end of dataIf this stream can not seek, it will return -1.
This function is not thread safe.
This function is available since SDL 3.2.0.
