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
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:
[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
