ACL_INIT(3) BSD Library Functions Manual ACL_INIT(3)NAMEacl_init — initialize ACL working storage
Linux Access Control Lists library (libacl, -lacl).
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 appropri‐
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 man‐
