Expand description

Writes a slice of bytes as the new contents of a file.

This function will create a file if it does not exist, and will entirely replace its contents if it does.


An error will be returned in the following situations:

  • The file’s parent directory does not exist.
  • The current process lacks permissions to write to the file.
  • Some other I/O error occurred.
