Linux Access Control Lists library (libacl, -lacl).


SYNOPSIS

     acl_t
     acl_init(int count)


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.


RETURN VALUE

     Upon successful completion, this function returns a pointer to the work­
     ing storage.  Otherwise, a value of (acl_t)NULL is returned, and errno is
     set to indicate the error.


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 al­
                   lowed by the hardware or system-imposed memory management
                   constraints.


STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
