    NAME

    
    
    acl_init
    
     - initialize ACL working storage
    
     
    

    LIBRARY

    Lb libc
    
     
    

    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. A pointer to the working storage is returned. The working storage allocated to contain the ACL is freed by a call to acl_free3. When the area is first allocated, it shall contain an ACL that contains no ACL entries.

    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 as an argument.  

    IMPLEMENTATION NOTES

    Fx Ns 's support for POSIX.1e interfaces and features is still under development at this time.  

    RETURN VALUES

    Upon successful completion, this function shall return a pointer to the working storage. Otherwise, a value of (acl_t)NULL shall be returned, and errno shall be set to indicate the error.  

    ERRORS

    If any of the following conditions occur, the acl_init ();
    function shall return a value of (acl_t)NULL and set 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

    POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the Fx POSIX.1e implementation page for more information.  

    HISTORY

    POSIX.1e support was introduced in Fx 4.0 , and development continues.
