            Bug ID: 29445
           Summary: Error in the documentation
           Product: glibc
           Version: 2.35
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: rmbeer2 at gmail dot com

  Target Milestone: ---

After reading and doing some tests to be sure, I have verified that the
documentation of open (man 2 open) is not correct.

- Make read only (O_RDONLY) don't give read and write mode (O_RDWR).
- Using O_CREAT don't modify again the modes of the file after being create=
d.
- Omit the third parameter, the mode get any garbage is make for the file.
- Write mode only work in the first time where the file is create, don't ma=
tter
if the file are create in no write mode.

I'm not sure how it should be fixed, or if any standard should be followed.
Perhaps only the modification of the operating details in the documentation=
 is
needed.
