Example:

// Deprecated: Use io.SeekStart, io.SeekCurrent, and io.SeekEnd.
const (
 SEEK_SET int = 0 // seek relative to the origin of the file
 SEEK_CUR int = 1 // seek relative to the current offset
 SEEK_END int = 2 // seek relative to the end
)

According to Constants at go.dev, SEEK_SET, SEEK_CUR, and SEEK_END are deprecated.
