FreeBSD 7.0 manual page repository

FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

      acl_delete_def_file, acl_delete_def_link_np, acl_delete_fd_np,
      acl_delete_file_np, acl_delete_link_np - delete an ACL from a file


      Standard C Library (libc, -lc)


      #include <sys/types.h>
      #include <sys/acl.h>
      acl_delete_def_file(const char *path_p);
      acl_delete_def_link_np(const char *path_p);
      acl_delete_fd_np(int filedes, acl_type_t type);
      acl_delete_file_np(const char *path_p, acl_type_t type);
      acl_delete_link_np(const char *path_p, acl_type_t type);


      The acl_delete_def_file(), acl_delete_def_link_np(), acl_delete_fd_np(),
      acl_delete_file_np(), and acl_delete_link_np() each allow the deletion of
      an ACL from a file.  The acl_delete_def_file() function is a POSIX.1e
      call that deletes the default ACL from a file (normally a directory) by
      name; the remainder of the calls are non-portable extensions that permit
      the deletion of arbitrary ACL types from a file/directory either by path
      name or file descriptor.  The _file() variations follow a symlink if it
      occurs in the last segment of the path name; the _link() variations oper‐
      ate on the symlink itself.
      FreeBSD’s support for POSIX.1e interfaces and features is still under
      development at this time.
      Upon successful completion, the value 0 is returned; otherwise the
      value -1 is returned and the global variable errno is set to indicate the


      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]           The ACL type passed is invalid for this file object.
      [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 points to an empty string.
      [ENOMEM]           Insufficient memory available to fulfill request.
      [ENOTDIR]          A component of the path prefix is not a directory.
                         Argument path_p must be a directory, and is not.
      [EOPNOTSUPP]       The file system does not support ACL deletion.
      [EPERM]            The process does not have appropriate privilege to
                         perform the operation to delete an ACL.
      [EROFS]            The file system is read-only.

      POSIX.1e is described in IEEE POSIX.1e draft 17.  Discussion of the draft
      continues on the cross-platform POSIX.1e implementation mailing list.  To

      POSIX.1e support was introduced in FreeBSD 4.0, and development contin‐

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
