[PATCH] Use nanosleep() instead of usleep()

[PATCH] Use nanosleep() instead of usleep()

[Daniel Mierswa]

[-- Attachment #1: Type: text/plain, Size: 501 bytes --]


POSIX.1-2001  declares usleep() function obsolete and POSIX.1-2008
removes it. Converted the calls to nanosleep().

I did a conditional replacement now with the same name.

Done too.

If you still don't like it, that's ok: that's why I'm boss. I simply know better than you do.

Subject: [PATCH] Use nanosleep() instead of usleep()

POSIX.1-2001  declares usleep() function obsolete and POSIX.1-2008
removes it. If usleep() is no longer present on a system, we use
nanosleep() instead.

What's the point doing that wrapping? Will usleep() ever be removed from glibc?

Well POSIX.1-2008 removes the specification and if you disable
UCLIBC_SUSV3_LEGACY in uClibc (which is default) you will get undefined
references. I don't think it's too big of a problem to replace it for
the cases where the C library doesn't offer it, is it?

If you still don't like it, that's ok: that's why I'm boss. I simply
know better than you do.

Why not just use nanosleep() unconditionally?

Here we go, reworked patch with unconditional replacement.

Subject: [PATCH] Use nanosleep() instead of usleep()

POSIX.1-2001  declares usleep() function obsolete and POSIX.1-2008
removes it. Replace all usleep code with nanosleep equivalent.
