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 corresponding 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 specified 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 argu-ment argument
                        ment 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.
