ACL_COPY_INT(3)         BSD Library Functions Manual         ACL_COPY_INT(3)

NAME         top

     acl_copy_int — copy an ACL from external to internal representation

LIBRARY         top

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

SYNOPSIS         top

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

     acl_t
     acl_copy_int(const void *buf_p);

DESCRIPTION         top

     The acl_copy_int() function copies an exportable, contiguous, persis‐
     tent form of an ACL, pointed to by buf_p, to the internal representa‐
     tion.

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

RETURN VALUE         top

     Upon success, the acl_copy_int() function returns a pointer that refer‐
     ences the ACL in working storage.  On error, a value of (acl_t)NULL is
     returned, and errno is set appropriately.

ERRORS         top

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

     [EINVAL]           The buffer pointed to by the argument buf_p does not
                        contain a valid external form ACL.

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

STANDARDS         top

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