NAME

       svc.conf - Database service selection configuration file

DESCRIPTION

       The  /etc/svc.conf  file  is  a	mandatory system file that allows you to select the desired services on a per database basis.  The default
       /etc/svc.conf file has local as the service selected for each database.	This file must be modified when adding or removing a  naming  ser-
       vice,  such  as	the  Network Information Service or BIND.  The valid services are local, yp, and bind.	Modifications to the /etc/svc.conf
       file can be made with an editor or the /usr/sbin/svcsetup command for database service selection.  Changes take	effect	immediately.   The
       recommended configuration is that you have local as the first entry for all databases.

RESTRICTIONS

       White space is allowed only after commas or newlines.

       You must have local as the first entry for the passwd and hosts databases.

       You must have yp as the entry for the netgroup database.

EXAMPLES

       The following is a sample /etc/svc.conf file: aliases=yp group=local,yp hosts=local,bind,yp netgroup=yp networks=local,yp passwd=local pro-
       tocols=local,yp rpc=local,yp services=local

Name
       getsvc - get a pointer to the svcinfo structure

Syntax
       #include <sys/svcinfo.h>

       struct svcinfo *getsvc()

Description
       The  call retrieves information from the system about the structure by returning a pointer to the structure.  This structure is initialized
       the first time a call is made.  The contents of the file are parsed and stored in the structure.  If the file is modified, the contents	of
       this structure will be updated upon the next call.

       The  file  contains the names of the databases that can be served by YP, BIND, or local files and the name service selection for each data-
       base.  It also has settings for four security parameters.  The database service selection and security parameters are stored in the  struc-
       ture.

       The following structure exists in the file:
       #define SVC_DATABASES 20
       #define SVC_PATHSIZE 8
       struct svcinfo {
	   int svcdate;       /* Last mod date of /etc/svc.conf */

	   int svcpath[SVC_DATABASES][SVC_PATHSIZE];	/* indexed by
				 databases and choice 0=first choice
			      1=second choice, etc value stored is
			source */

	      struct {
		  int passlenmin;
		  int passlenmax;
		  int softexp;
		  int seclevel;
	      } svcauth;
       };

       The field contains the date that the file was last modified.  The array contains the name service choices for each database.  The structure
       contains the values for the four security parameters: password length minimum (passlenmin),  password  length  maximum  (passlenmax),  soft
       expiration date of a password (softexp), and security mode of a system (seclevel).

Examples
       The following programming example shows how to use the call to use the information in the structure to process specific host information.
       #include <sys/svcinfo.h>
       struct svcinfo *svcinfo;

       if ((svcinfo = getsvc()) != NULL)
	 for (i=0; (j = svcinfo->svcpath[SVC_HOSTS][i]) != SVC_LAST; i++)
	     switch(j) {
		 case SVC_BIND:
		     /* process BIND hosts */
		 case SVC_YP:
		     /* process YP hosts */
		 case SVC_LOCAL:
		  /* process LOCAL hosts */
	     }
