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

     acl_set_fd — set an ACL by file descriptor

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

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

     acl_set_fd(int fd, acl_t acl);

     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 suc‐

     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.

     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.
