SDL_RWseek

Seek within an SDL_RWops data stream.

Syntax

Sint64 SDL_RWseek(SDL_RWops *context,
                  Sint64 offset, int whence);

Function Parameters

context a pointer to an SDL_RWops structure
offset an offset in bytes, relative to whence location; can be negative
whence any of RW_SEEK_SET, RW_SEEK_CUR, RW_SEEK_END

Return Value

Returns the final offset in the data stream after the seek or -1 on error.

Remarks

This function seeks to byte offset, relative to whence.

whence may be any of the following values:

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

SDL_RWseek() is actually a wrapper function that calls the SDL_RWops's seek method appropriately, to simplify application development.

Prior to SDL 2.0.10, this function was a macro.

Version

This function is available since SDL 2.0.10.
