Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
acl_t
acl_copy_int(const void *buf_p)
DESCRIPTION
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 argu
ment.
RETURN VALUE
Upon successful completion, the acl_copy_int() function returns a pointer
that references the ACL in working storage. Otherwise, a value of
(acl_t)NULL is returned, and errno is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_copy_int() function re
turns 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 con
tain a valid external form ACL.
[ENOMEM] The ACL working storage requires more memory than is al
lowed by the hardware or system-imposed memory management
constraints.
STANDARDS
