acl_init — initialize ACL working storage
Contents
Description
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.
Errors
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.
Library
Linux Access Control Lists library (libacl, -lacl).
