Is Solaris eaccess the same as euidaccess? Should glibc provide eaccess as
an alias for euidaccess?
Except on the Hurd, euidaccess actually either just uses access (when r==e)
or uses stat and the usual st_mode rules assuming those are what the
filesystem will actually use, which you can do yourself. rm et al I expect
are never setuid and so can always use the method of calling access, which
is superior in telling truth about permission, but lacks the *at features.
In keeping with the other interfaces, it should be faccessat and use a new
AT_* flag bit to distinguish real-user from effective-user access checking.
int faccessat (int fd, const char *file, int type, int flag);
Does that sound reasonable?
Thanks,
Roland
