seek

seek(s, pos)

Seek a stream to the given position.

Examples

In the Julia programming language, the function seek(s, pos) is used to seek a stream to the given position.

julia> io = IOBuffer("Hello, Julia!");
julia> seek(io, 7)
7

In this example, the seek function is used to seek the stream io to position 7.

Common examples of its use:

Seek to the beginning of a file:
```
julia> file = open("data.txt", "r");
julia> seek(file, 0)
0
```
It seeks the file to the beginning by setting the position to 0.
Seek to a specific position in a file:
```
julia> file = open("data.txt", "r");
julia> seek(file, 100)
100
```
It seeks the file to position 100.
Seek to the end of a file:
```
julia> file = open("data.txt", "r");
julia> seekend(file)
500
```
It seeks the file to the end by using the seekend function.

Common mistake example:

julia> io = IOBuffer("Hello, Julia!");
julia> seek(io, 20)
ERROR: ArgumentError: invalid seek position

In this example, the seek position provided is beyond the available data in the stream. It is important to ensure that the seek position is within the valid range of the stream to avoid such errors. Always validate the seek position before using the seek function.
