    Command:

    acl_dup

    
    
    
    

    SYNOPSIS

         #include <sys/types.h>
         #include <sys/acl.h>
    
         acl_t
         acl_dup(acl_t acl);
    
    
    

    DESCRIPTION

         The acl_dup() function returns a pointer to a copy of the ACL pointed to
         by acl.
    
         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_dup() 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 appropri-
         ately.
    
    
    

    ERRORS

         If any of the following conditions occur, the acl_dup() function returns
         a value of (acl_t)NULL and sets errno to the corresponding value:
    
         [EINVAL]           The argument acl is not a valid pointer to an ACL.
    
         [ENOMEM]           The acl_t to be returned requires more memory than is
                            allowed by the hardware or system-imposed memory man-
                            agement constraints.
