opens a file for write only access. LogFile is a file descriptor (an integer).
the 06666 sets the protections on the new file.

open returns a (-1) when it fails, so the function returns 1 on failure.

The open() system call opens a file descriptor for the named file and
sets the file status flags according to the value of oflag.

check "man open"
