.SH NAME
SDL_SeekIO \- Seek within an 
.BR SDL_IOStream
 data stream\[char46]
.SH HEADER FILE
Defined in SDL3/SDL_iostream\[char46]h

.SH SYNOPSIS
.nf
.B #include \(dqSDL3/SDL.h\(dq
.PP
.BI "Sint64 SDL_SeekIO(SDL_IOStream *context, Sint64 offset, SDL_IOWhence whence);
.fi
.SH DESCRIPTION
This function seeks to byte
.BR offset
, relative to
.BR whence
\[char46]
.BR whence
may be any of the following values:


\(bu 
.BR
.BR SDL_IO_SEEK_SET
: seek from the beginning of data

\(bu 
.BR
.BR SDL_IO_SEEK_CUR
: seek relative to current read point

\(bu 
.BR
.BR SDL_IO_SEEK_END
: seek relative to the end of data

If this stream can not seek, it will return -1\[char46]

.SH FUNCTION PARAMETERS
.TP
.I context
a pointer to an 
.BR SDL_IOStream
 structure\[char46]
.TP
.I offset
an offset in bytes, relative to
.BR whence
location; can be negative\[char46]
.TP
.I whence
any of 
.BR
.BR SDL_IO_SEEK_SET
, 
.BR
.BR SDL_IO_SEEK_CUR
, 
.BR
.BR SDL_IO_SEEK_END
\[char46]
.SH RETURN VALUE
(
.BR Sint64
) Returns the final offset in the data stream after the
seek or -1 on failure; call 
.BR SDL_GetError
() for more
information\[char46]

.SH THREAD SAFETY
This function is not thread safe\[char46]

.SH AVAILABILITY
This function is available since SDL 3\[char46]2\[char46]0\[char46]
