GETNETCONFIG(3)		 BSD Library Functions Manual	       GETNETCONFIG(3)

NAME
     getnetconfig, setnetconfig, endnetconfig, getnetconfigent,
     freenetconfigent, nc_perror, nc_sperror — get network configuration data‐
     base entry

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <netconfig.h>

     struct netconfig *
     getnetconfig(void *handlep);

     void *
     setnetconfig(void);

     int
     endnetconfig(void *handlep);

     struct netconfig *
     getnetconfigent(const char *netid);

     void
     freenetconfigent(struct netconfig *netconfigp);

     void
     nc_perror(const char *msg);

     char *
     nc_sperror(void);

DESCRIPTION
     The library routines described on this page provide the application
     access to the system network configuration database, /etc/netconfig.  The
     getnetconfig() function returns a pointer to the current entry in the
     netconfig database, formatted as a struct netconfig.  Successive calls
     will return successive netconfig entries in the netconfig database.  The
     getnetconfig() function can be used to search the entire netconfig file.
     The getnetconfig() function returns NULL at the end of the file.  The
     handlep argument is the handle obtained through setnetconfig().

     A call to setnetconfig() has the effect of “binding” to or “rewinding”
     the netconfig database.  The setnetconfig() function must be called
     before the first call to getnetconfig() and may be called at any other
     time.  The setnetconfig() function need not be called before a call to
     getnetconfigent().	 The setnetconfig() function returns a unique handle
     to be used by getnetconfig().

     The endnetconfig() function should be called when processing is complete
     to release resources for reuse.  The handlep argument is the handle
     obtained through setnetconfig().  Programmers should be aware, however,
     that the last call to endnetconfig() frees all memory allocated by
     getnetconfig() for the struct netconfig data structure.  The
     endnetconfig() function may not be called before setnetconfig().

     The getnetconfigent() function returns a pointer to the netconfig struc‐
     ture corresponding to netid.  It returns NULL if netid is invalid (that
     is, does not name an entry in the netconfig database).

     The freenetconfigent() function frees the netconfig structure pointed to
     by netconfigp (previously returned by getnetconfigent()).

     The nc_perror() function prints a message to the standard error indicat‐
     ing why any of the above routines failed.	The message is prepended with
     the string msg and a colon.  A newline character is appended at the end
     of the message.

     The nc_sperror() function is similar to nc_perror() but instead of send‐
     ing the message to the standard error, will return a pointer to a string
     that contains the error message.

     The nc_perror() and nc_sperror() functions can also be used with the
     NETPATH access routines defined in getnetpath(3).

RETURN VALUES
     The setnetconfig() function returns a unique handle to be used by
     getnetconfig().  In the case of an error, setnetconfig() returns NULL and
     nc_perror() or nc_sperror() can be used to print the reason for failure.

     The getnetconfig() function returns a pointer to the current entry in the
     netconfig database, formatted as a struct netconfig.  The getnetconfig()
     function returns NULL at the end of the file, or upon failure.

     The endnetconfig() function returns 0 on success and -1 on failure (for
     example, if setnetconfig() was not called previously).

     On success, getnetconfigent() returns a pointer to the struct netconfig
     structure corresponding to netid; otherwise it returns NULL.

     The nc_sperror() function returns a pointer to a buffer which contains
     the error message string.	This buffer is overwritten on each call.  In
     multithreaded applications, this buffer is implemented as thread-specific
     data.
