Bug ID: 60744
Summary: waitid man page does not document the 5th argument
"struct rusage*"
Product: Documentation
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: man-pages
Assignee: documentation_man-pages-ztI5WcYan/vQLgFONoPN62D2FQJk+8+b@public.gmane.org
Reporter: hannes-AXwPPc4i43WoxJ3sLSulrA@public.gmane.org
Regression: No
I just spent 5 hours debugging my program and trying to figure out why the
kernel overwrote my stack. I had to read the source code to realize that the
real syscall took an additional 5th argument.
Wrong signature:
int waitid(idtype_t idtype, id_t id, siginfo_t *infop, int options);
Correct signature:
int waitid(idtype_t idtype, id_t id, siginfo_t *infop, int options, struct
rusage* rusage);
The kernel man pages should not assume that the user is using glibc, or at
least give enough information for developers to write their own, correct
wrappers.
