skip

skip(s, offset)

Seek a stream relative to the current position.

Examples

In the Julia programming language, the skip function is used to seek a stream relative to the current position. It allows you to skip a specified number of bytes or characters from the current position in the stream. It returns the updated stream after skipping.

julia> io = IOBuffer("Hello, World!")
julia> skip(io, 7)
IOBuffer(data=UInt8[...], readable=true, writable=false, seekable=true, append=false, size=13, maxsize=Inf, ptr=8, mark=-1)

Here are some common examples of how to use the skip function:

1. Skip a specific number of bytes in a file:

   julia> file = open("data.txt", "r")
   julia> skip(file, 10)

   This example skips 10 bytes from the current position in the file.

2. Skip a specific number of characters in a string:

   julia> str = "Julia Programming"
   julia> skip(str, 6)

   It skips 6 characters from the current position in the string.

3. Skip to the end of the stream:

   julia> io = IOBuffer("Hello, World!")
   julia> skip(io, eof)

   This example skips to the end of the stream.

Common mistake example:

julia> io = IOBuffer("Hello, World!")
julia> skip(io, -5)
ERROR: InexactError: Int64(-5)

In this example, a negative offset is provided to the skip function. The offset should be a non-negative value. Make sure to provide a valid offset to avoid errors while using the skip function.
