Summary	0001666: getresgid() and getresuid() are missing "restrict"
Description	These functions modify multiple values of the same type via pointers passed as arguments, and there is no reason to allow applications to pass the same pointer value in two or more arguments, so the functions should have "restrict" in their prototypes.
Desired Action	On page 470 line 16562,16563 section <unistd.h>, change: int getresgid(gid_t , gid_t , gid_t ); int getresuid(uid_t , uid_t , uid_t ); to: int getresgid(gid_t restrict, gid_t restrict, gid_t restrict); int getresuid(uid_t restrict, uid_t restrict, uid_t restrict); On page 1170 line 40031 section getresgid(), change: int getresgid(gid_t rgid, gid_t egid, gid_t sgid); to: int getresgid(gid_t restrict rgid, gid_t restrict egid, gid_t restrict sgid); On page 1171 line 40061 section getresgid(), change: int getresuid(uid_t ruid, uid_t euid, uid_t suid); to: int getresuid(uid_t restrict ruid, uid_t restrict euid, uid_t restrict suid);

shware_systems 2023-06-08 16:20 reporter bugnote:0006315	During the discussion of this it was noted there was a chance some existing code might break with this change, but it was felt the increase in portability was enough to offset this for the long run.
