The number should be high, but exceeding it may degrade Note: The maximum number of concurrent operations on a File may be limited by

Write take their byte counts from the length of the argument slice.įmt.Printf("read %d bytes: %q\n", count, data) The file's data can then be read into a slice of bytes. If the open fails, the error string will be self-explanatory, like Here is a simple example, opening a file and reading some of it.įile, err := os.Open("file.go") // For read access. The os interface is intended to be uniform across all operating systems.įeatures not generally available appear in the system-specific package syscall. *PathError, which may be unpacked for more information. Will include the failing file name when printed and will be of type If a call that takes a file name fails, such as Open or Stat, the error Often, more information is available within the error. Go-like failing calls return values of type error rather than error numbers. The design is Unix-like, although the error handling is Package os provides a platform-independent interface to operating systemįunctionality. Go – os Index | Examples | Files | Directories package os
