(This is the legacy documentation for stable SDL2, the current stable version; SDL3 is the current development version.)

SDL_RWtell

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

Header File

Defined in SDL_rwops.h

Syntax

Sint64 SDL_RWtell(SDL_RWops *context);

Function Parameters

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

Return Value

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.
