    Command:

    getnetpath

    
         Standard C Library (libc, -lc)
    
    
    

    SYNOPSIS

         #include <netconfig.h>
    
         struct netconfig *
         getnetpath(void *handlep);
    
         void *
         setnetpath(void);
    
         int
         endnetpath(void *handlep);
    
    
    

    DESCRIPTION

         The routines described in this page provide the application access to the
         system network configuration database, /etc/netconfig, as it is
         "filtered" by the NETPATH environment variable (see environ(7)).  See
         getnetconfig(3) for other routines that also access the network configu-
         ration database directly.  The NETPATH variable is a list of colon-sepa-
         rated network identifiers.
    
         The getnetpath() function returns a pointer to the netconfig database
         entry corresponding to the first valid NETPATH component.  The netconfig
         entry is formatted as a struct netconfig.  On each subsequent call,
         getnetpath() returns a pointer to the netconfig entry that corresponds to
         the next valid NETPATH component.  The getnetpath() function can thus be
         used to search the netconfig database for all networks included in the
         NETPATH variable.  When NETPATH has been exhausted, getnetpath() returns
         NULL.
    
         A call to setnetpath() "binds" to or "rewinds" NETPATH.  The setnetpath()
         function must be called before the first call to getnetpath() and may be
         called at any other time.  It returns a handle that is used by
         getnetpath().
    
         The getnetpath() function silently ignores invalid NETPATH components.  A
         NETPATH component is invalid if there is no corresponding entry in the
         netconfig database.
    
         If the NETPATH variable is unset, getnetpath() behaves as if NETPATH were
         set to the sequence of "default" or "visible" networks in the netconfig
         database, in the order in which they are listed.
    
         The endnetpath() function may be called to "unbind" from NETPATH when
         processing is complete, releasing resources for reuse.  Programmers
         should be aware, however, that endnetpath() frees all memory allocated by
         getnetpath() for the struct netconfig data structure.
    
    
    

    RETURN VALUES

         The setnetpath() function returns a handle that is used by getnetpath().
         In case of an error, setnetpath() returns NULL.
