NAME

       acl_get_fd - Retrieves the specified ACL associated with the specified file or directory

LIBRARY

       Security Library (libpacl.a)

SYNOPSIS

       #include <sys/acl.h>
       acl_t acl_get_fd(      int fd);	    acl_type_t type_d);

PARAMETERS

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

       The  required  access  to  the file or directory was denied.  The fd argument is not a valid file descriptor.  The argument type_d is not a
       recognized ACL type.  There is not enough memory available to the process to allocate the working storage.  The type_d argument indicates a
       default ACL, and fd does not point to a directory.

NAME

     acl_get_fd -- get an ACL by file descriptor

LIBRARY

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

SYNOPSIS

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

     acl_t
     acl_get_fd(int fd);

DESCRIPTION

     The acl_get_fd() function retrieves the access ACL associated with the file referred to by fd.  The ACL is placed into working storage and
     acl_get_fd() returns a pointer to that storage.

     In order to read an ACL from an object, a process must have read access to the object's attributes.

     This function may cause memory to be allocated.  The caller should free any releasable memory, when the new ACL is no longer required, by
     calling acl_free(3) with the (void*)acl_t returned by acl_get_fd() as an argument.

RETURN VALUE

     Upon successful completion, this function shall return a pointer to the working storage.  Otherwise, a value of (acl_t)NULL shall be
     returned, and errno shall be set to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_get_fd() function returns a value of (acl_t)NULL and sets errno to the corresponding value:

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

     [ENOMEM]		The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management con-
			straints.

     [ENOTSUP]		The file system on which the file identified by fd is located does not support ACLs, or ACLs are disabled.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
