ACL_INIT(3)             BSD Library Functions Manual             ACL_INIT(3)

NAME         top

     acl_init — initialize ACL working storage

LIBRARY         top

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

SYNOPSIS         top

     #include <sys/types.h>
     #include <sys/acl.h>
     acl_t
     acl_init(int count);

DESCRIPTION         top

     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 call‐
     ing acl_free(3) with the (void*)acl_t returned by acl_init() as an
     argument.

RETURN VALUE         top

     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‐
     ately.

ERRORS         top

     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.

STANDARDS         top

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