SDL_RWtell

Determine the current read/write offset in an SDL_RWops data stream.

Header File

Syntax

Sint64 SDL_RWtell(SDL_RWops *context);

Function Parameters

SDL_RWops *

context

a SDL_RWops data stream object from which to get the current offset.

Return Value

(Sint64) Returns the current offset in the stream, or -1 if the information can not be determined.

Remarks

SDL_RWtell is actually a wrapper function that calls the SDL_RWops's seek method, with an offset of 0 bytes from RW_SEEK_CUR, 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.
