acl_copy_int — copy an ACL from external to internal representation

Derived from the FreeBSD manual pages written by Robert N M Watson <rwatson@FreeBSD.org>, and adapted for Linux by Andreas Gruenbacher <andreas.gruenbacher@gmail.com>. Linux ACL March 23, 2002 ACL_COPY_INT(3)

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.

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.

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.
