int acl_strip(const char *path, uid_t uid, gid_t gid, mode_t mode);

The acl_strip() function removes all ACLs from a file and replaces them with a trivial ACL based on the mode argument. After replacing the ACL, the owner and group of the file are set to the values specified by the uid and gid arguments.

Return Values

Upon successful completion, acl_strip() returns 0. Otherwise it returns –1 and sets errno to indicate the error.

The acl_strip() function will fail if:

EACCES

EINVAL

The uid or gid argument is out of range.

EIO

A disk I/O error has occurred while storing or retrieving the ACL.

ELOOP

A loop exists in symbolic links encountered during the resolution of the path argument.

ENAMETOOLONG

The length of the path argument exceeds {PATH_MAX}, or the length of a path component exceeds {NAME_MAX} while _POSIX_NO_TRUNC is in effect.

ENOENT

A component of path does not exist.
