ACL_COPY_INT(3) BSD Library Functions Manual ACL_COPY_INT(3)
acl_copy_int — copy an ACL from external to internal representation
Linux Access Control Lists library (libacl, -lacl).
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_copy_int(const void *buf_p);
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.
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.
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.
