    NAME

    acl_init
    
     - initialize ACL working storage
    
     
    

    LIBRARY

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

    SYNOPSIS

       #include <sys/types.h>
       #include <sys/acl.h>
    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_free3 with the (void*)acl_t returned by acl_init ();
    as an argument.  

    RETURN VALUE

    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.  

    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:

    Bq Er EINVAL
    The value of count is less than zero.
    Bq Er ENOMEM
    The acl_t to be returned requires more memory than is allowed by the hardware or system-imposed memory management constraints.

     

    STANDARDS

    IEEE Std 1003.1e draft 17 (lqPOSIX.1erq, abandoned)
