acl_get_fd(3)
NAME
  acl_get_fd - Retrieves the specified ACL associated with the specified file
  or directory

SYNOPSIS
  #include <sys/acl.h>

  acl_t acl_get_fd(
	  int fd,
	  acl_type_t type_d );

LIBRARY
  Security Library (libpacl.a)

PARAMETERS
  fd  Designates the file descriptor of the file or directory to retrieve the
      ACL from.

  type_d
      Designates the type of ACL to retrieve: ACL_TYPE_ACCESS,
      ACL_TYPE_DEFAULT, or ACL_TYPE_DEFAULT_DIR.

DESCRIPTION
  NOTE:	 This function is based on Draft 13 of the POSIX P1003.6 standard.

  The acl_get_fd() function retrieves the specified ACL for the given file
  descriptor. The acl_tag_t field designates if the ACL being retrieved is an
  access or default ACL. Working storage is allocated as needed.

RETURN VALUES
  Upon successful completion, the acl_get_fd() function returns a pointer to
  the working storage internal representation copy of the ACL. If the
  specified ACL type is ACL_TYPE_DEFAULT or ACL_TYPE_DEFAULT_DIR and the
  specified ACL doesn't exist for the given file descriptor a value of NULL
  is returned.	If the specified ACL type is ACL_TYPE_ACCESS and the given
  file descriptor doesn't have an access ACL a pointer to the working storage
  internal representation copy of the permission bits in ACL format is
  returned. Otherwise, a value of NULL is returned and errno is set to
  indicate the error.

ERRORS
  If any of the following conditions occur, the acl_get_fd() function sets
  errno to the corresponding value:

  [EACCES]
      The required access to the file or directory was denied.

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

  [EINVAL]
      The argument type_d is not a recognized ACL type.

  [ENOMEM]
      There is not enough memory available to the process to allocate the
      working storage.

  [ENOTDIR]
      The type_d argument indicates a default ACL, and fd does not point to a
      directory.
