ACL_INIT(3) Library Functions Manual ACL_INIT(3)
acl_init — initialize ACL working storage
Linux Access Control Lists library (libacl, -lacl).
<sys/types.h> <sys/acl.h> acl_t acl_init(int count)
The acl_init() function allocates and initializes the working
storage for an ACL of at least count ACL entries. The ACL created
initially contains no ACL entries. A pointer to the working
storage is returned.
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_init() as an argument.
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.
If any of the following conditions occur, the acl_init() function
returns a value of (acl_t)NULL and sets errno to the corresponding
value:
[EINVAL] The value of count is less than zero.
[ENOMEM] The acl_t to be returned requires more memory
than is allowed by the hardware or system-
imposed memory management constraints.
