ACL_SET_FD(3)             BSD Library Functions Manual             ACL_SET_FD(3)

NAME
     acl_set_fd — set an ACL by file descriptor

LIBRARY
     Linux Access Control Lists library (libacl, -lacl).

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

     int
     acl_set_fd(int fd, acl_t acl);

DESCRIPTION
     The acl_set_fd() function associates an access ACL with the file referred
     to by fd.

     The effective user ID of the process must match the owner of the file or
     the process must have the CAP_FOWNER capability for the request to succeed.

RETURN VALUE
     The acl_set_fd() function returns the value 0 if successful; 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, the acl_set_fd() function returns
     the value -1 and and sets errno to the corresponding value:

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

     [EINVAL]           The argument acl does not point to a valid ACL.

                        The ACL has more entries than the file referred to by fd
                        can obtain.

     [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.

     [ENOTSUP]          The file identified by fd cannot be associated with the
                        ACL because the file system on which the file is located
                        does not support this.

     [EPERM]            The process does not have appropriate privilege to
                        perform the operation to set the ACL.

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

STANDARDS
