man acl_dup (Fonctions bibliothèques) - acl_dup
NAME
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
DESCRIPTION
The acl_dup function returns a pointer to a copy of the ACL pointed to by acl .
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() with the (void*)acl_t returned by acl_dup as an argument.
RETURN VALUE
On success, this function returns a pointer to the 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 acl_dup function returns a value of (acl_t)NULL and sets errno to the corresponding value:
- Bq EINVAL
- The argument acl is not a valid pointer to an ACL.
- Bq ENOMEM
- The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.
STANDARDS
IEEE Std 1003.1e draft 17 (POSIX.1e, abandoned)
