acl_copy_int (3)

    Linux ACL  

    NAME

    acl_copy_int
    
     - copy an ACL from external to internal representation
    
     
    

    LIBRARY

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

    SYNOPSIS

       #include <sys/types.h>
       #include <sys/acl.h>
    acl_t acl_copy_int (const void *buf_p);
     

    DESCRIPTION

    The acl_copy_int ();
    function copies an exportable, contiguous, persistent form of an ACL, pointed to by buf_p to the internal representation.

    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_copy_int ();
    as an argument.  

    RETURN VALUE

    Upon success, the acl_copy_int ();
    function returns a pointer that references the ACL in 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_copy_int ();
    function returns a value of (acl_t)NULL and sets errno to the corresponding value:

    Bq Er EINVAL
    The buffer pointed to by the argument buf_p does not contain a valid external form ACL.
    Bq Er ENOMEM
    The ACL working storage 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)
