SDL_IOWhence.3type - Man Page

#include <SDL3/SDL_iostream.h>

typedef enum SDL_IOWhence
{
    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 */
} SDL_IOWhence;

These map to the same "whence" concept that fseek or lseek use in the standard C runtime.

This enum is available since SDL 3.2.0.
