Bug ID: 202545
Summary: A small change suggestion for the manual page fopen(3)
Product: Documentation
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: Documentation
Assignee: [email protected]
Reporter: [email protected]
As so people know, fopen("/path/to/xxxxx.xxx", "w") empties the file if it
exists. I believe that the FreeBSD manual page fopen(3) needs to mention it.
The corresponding POSIX manual page fopen(3p) says:
w or wb Truncate to zero length or create file for writing.
The corresponding Linux manual page fopen(3) says:
w Truncate file to zero length or create text file for writing. The
stream is positioned at the beginning of the file.
The following patch is against:
