ACL_SET(3)               BSD Library Functions Manual               ACL_SET(3)

NAME
     acl_set_fd, acl_set_fd_np, acl_set_file, acl_set_link_np -- set an ACL for a file

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_set_fd(int fd, acl_t acl);

     int
     acl_set_fd_np(int fd, acl_t acl, acl_type_t type);

     int
     acl_set_file(const char *path_p, acl_type_t type, acl_t acl);

     int
     acl_set_link_np(const char *path_p, acl_type_t type, acl_t acl);

DESCRIPTION
     The acl_set_fd(), acl_set_fd_np(), acl_set_file(), and acl_set_link_np() each associate an ACL with an
     object referred to by fd or path_p.  The acl_set_fd_np() and acl_set_link_np() functions are not
     POSIX.1e calls.  The acl_set_fd() function allows only the setting of ACLs of type ACL_TYPE_EXTENDED
     where as acl_set_fd_np() allows the setting of ACLs of any type.  The acl_set_link_np() function acts
     on a symlink rather than its target, if the target of the path is a symlink.

RETURN VALUES
     Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global
     variable errno is set to indicate the error.

ERRORS
     If any of the following conditions occur, these functions shall return -1 and set errno to the corre-sponding corresponding
     sponding value:

     [EACCES]           Search permission is denied for a component of the path prefix, or the object exists
                        and the process does not have appropriate access rights.

     [EBADF]            The fd argument is not a valid file descriptor.

     [EINVAL]           Argument acl does not point to a valid ACL for this object, or the ACL type speci-fied specified
                        fied in type is invalid for this object, or both.

     [ENAMETOOLONG]     A component of a pathname exceeded 255 characters, or an entire path name exceeded
                        1023 characters.

     [ENOENT]           The named object does not exist, or the path_p argument points to an empty string.

     [ENOMEM]           Insufficient memory available to fulfill request.

     [ENOSPC]           The directory or file system that would contain the new ACL cannot be extended, or
                        the file system is out of file allocation resources.

     [EOPNOTSUPP]       The file system does not support ACL retrieval.

     [EROFS]            This function requires modification of a file system which is currently read-only.
