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 sup-
                        port 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 cur-
                        rently read-only.

STANDARDS
