Hi maintainers, the manual of function thrd_sleep as documented in thrd_create.3 in package devel/libstdthreads contains incorrect information. The same page is served at man.freebsd.org and contains the same incorrect return value section there as well. I think this should be fixed. Following that manual one is lead to checking for thrd_success which happens to be zero on some platforms, but not BSD. Reading that manual should not lead to broken code only working by accident on other platforms but BSD.
