LIBRARY
Linux Access Control Lists library (libacl, -lacl).SYNOPSIS
In sys/types.h In sys/acl.h Ft acl_t Fn acl_copy_int const void *buf_pDESCRIPTION
The Fn 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_free3 with the (void*)acl_t returned by Fn acl_copy_int as an argument.
RETURN VALUE
Upon success, the Fn 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.ERRORS
If any of the following conditions occur, the Fn acl_copy_int function returns a value of (acl_t)NULL and sets errno to the corresponding value:- Bq Er EINVAL
- The buffer pointed to by the argument buf_p does not contain a valid external form ACL.
- Bq Er ENOMEM
- The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
