Subject: [Bug 218600] New: printf family returns number of bytes written, not characters
Date: Thu, 14 Mar 2024 22:16:38 +0000 [thread overview]
Message-ID: <bug-218600-11311@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=218600
Bug ID: 218600
Summary: printf family returns number of bytes written, not
characters
Product: Documentation
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: low
Priority: P3
Component: man-pages
Assignee: documentation_man-pages@kernel-bugs.osdl.org
Reporter: quirin.blaeser@freenet.de
Regression: No
For comparison:
https://pubs.opengroup.org/onlinepubs/9699919799/
In an utf8 environment the number of bytes written may differ
from the number of characters.
Example:
fprintf( stdout, "%*s\n", fprintf( stdout, "öäüÖÄÜßµł€\n"), "^");
From https://man7.org/linux/man-pages/man3/dprintf.3.html:
"Upon successful return, these functions return the number of
characters printed (excluding the null byte used to end output to
strings)."
Greetings.
