FreeBSD 4.7 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_fd_np, acl_delete_file_np - delete an ACL



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


      library “libposix1e”


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


      The acl_delete_def_file(), acl_delete_file_np(), and acl_delete_fd_np()
      each allow the deletion of an ACL from a file.  acl_delete_def_file() is
      a POSIX.1e call that deletes the default ACL from a file (normally a
      directory) by name; the other two calls are non-portable extensions that
      allow deleting of arbitrary ACL types from a file/directory by either
      path name, or by file descriptor.
      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
      join this list, see the FreeBSD POSIX.1e implementation page for more


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

      These features are not yet fully implemented.  In particular, the shipped
      version of UFS/FFS does not support storage of additional security
      labels, and so is unable to (easily) provide support for most of these


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.
