NAME
       setservent, setservent_r - Open or rewind the services file

LIBRARY
       Standard C Library (libc.so, libc.a)

SYNOPSIS
       #include <netdb.h>
       void setservent(      int stay_open);

       [Tru64  UNIX]  The following function is supported in order to maintain backward compatibility with previous versions of the operating sys-
       tem.  int setservent_r(	    int stay_open,	struct servent_data *serv_data);

       [Tru64 UNIX]  The following function is supported in order to maintain backward compatibility with previous versions of the operating  sys-
       tem.

       int setservent(	    int stay_open);

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       setservent():  XNS4.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS
       Indicates when to close the services file.  Specifying a value of 0 (zero) causes the file to be closed after each call to the getservent()
       function.  Specifying a nonzero value allows the file to remain open after each call.  [Tru64 UNIX]  Points to a  structure  where  setser-
       vent_r() stores information about the services file.

DESCRIPTION
       The  setservent() (set service entry) function opens either the local /etc/services file or the NIS distributed services file, and sets the
       file marker at the beginning of the file. To determine which file or files to search, and in which order, the system uses the  switches	in
       the /etc/svc.conf file.

NOTES
       [Tru64  UNIX]  The  setservent_r()  function  is  the reentrant version of the setservent() function.  It is supported in order to maintain
       backward compatibility with previous versions of the operating system.  Upon successful completion, the setservent_r() function	returns  a
       value of 0 (zero).  Otherwise, it returns a value of -1.

       [Tru64  UNIX]  Before  calling  the setservent_r() function for the first time, you must zero-fill the servent_data structure.  The netdb.h
       header file defines the servent_data structure.

RETURN VALUES
       Current industry standards for setservent() do not define return values.

       [Tru64 UNIX]  Upon successful completion, the setservent() function included for backward compatibility returns a 1  for  success.   Other-
       wise, it returns a value of 0 (zero).

ERRORS
       Current industry standards for setservent() do not define error values.

       [Tru64 UNIX]  If any of the following conditions occurs, the setservent_r() function sets errno to the corresponding value: If serv_data is
       invalid.

       In addition, the setservent() and setservent_r() functions can fail to open the file.  In this case, errno will be set to the failure.

FILES
       Contains service names.	The database service selection configuration file.
