ACL_GET_FD(3)            Library Functions Manual          ACL_GET_FD(3)

ИМЯ

       acl_get_fd — get an ACL by file descriptor

БИБЛИОТЕКА

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

СИНТАКСИС

       <sys/types.h> <sys/acl.h> acl_t acl_get_fd(int fd)

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ ВОЗВРАТА

       On success, this function shall return a pointer to the working
       storage.  On error, a value of (acl_t)NULL shall be returned, and
       errno is set appropriately.

ОШИБКИ

       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 constraints.

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