acl_copy_int — copy an ACL from external to internal representation
Linux Access Control Lists library (libacl, -lacl).
acl_copy_int(const void *buf_p);
The acl_copy_int() function copies an exportable, contiguous, persistent form of an ACL, pointed to by buf_p, to the internal representation.
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_copy_int() as an argument.
Upon success, the acl_copy_int() function returns a pointer that references the ACL in working storage. On error, a value of
(acl_t)NULL is returned, and errno is set appropriately.
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:
- The buffer pointed to by the argument buf_p does not contain a valid external form ACL.
- The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
