Public bug reported:
Multiple packages suspected
manpages-dev
libc6
The system call "clock_nanosleep" does not have documentation, and I
cannot determine if it is supposed to exist or not.
Release: 8.10 Intrepid Ibex
Updated thru March 1 2009
Package versions:
libc6: 2.8~20080505-0ubuntu9
manpages-dev: 3.01-1
Expected result: diagnostics about proper usage. Either ENOSYS or
EINVAL would have tested if the function in question was defined in the
kernel, or a compiler error compalining about clock_nanosleep not being
declared
Actual result: a linker error claiming that clock_nanosleep was not
defined
test case:
#include <test.h>
int main()
{
clock_nanosleep(0, 0, 0, 0);
}
What I think should have happened:
If the system call didn't exist, the macro enabling its declaration
__USE_XOPEN2K, should not have been defined, and the compiler should
have choked instead of the linker.
If the system call does exist, it should have a manpage. If it doesn't,
then it shouldn't be declared in the first place.
There is a problem with either
1) The manpages and the libc6 both omitting this function when the time.h file
declares it
2) Feature macros that erroneously enable this
I don't know which the case is. The reference to this function in
time(7) manpage suggests its existence at large. Whether or not it
does, or is supposed to, in my libs and kernel, is unknown.
