[PATCH v4 03/13] bisect--helper: introduce new `write_in_file()` function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Let's refactor code adding a new `write_in_file()` function
that opens a file for writing a message and closes it and a
wrapper for writting mode.

This helper will be used in later steps and makes the code
simpler and easier to understand.
