SLPOpen(3SLP)					    Service Location Protocol Library Functions 				     SLPOpen(3SLP)

NAME

       SLPOpen - open an SLP handle

SYNOPSIS

       #include <slp.h>

       SLPError SLPOpen(const char *pcLang, SLPBoolean isAsync, SLPHandle *phSLP);

DESCRIPTION

       The  SLPOpen()  function  returns  a  SLPHandle	handle in the phSLP parameter  for  the  language   locale  passed   in  as   the   pcLang
       parameter.  The client indicates if operations on  the  handle are  to be synchronous
	or asynchronous  through  the isAsync  parameter.  The	handle encapsulates  the  language locale  for SLP requests  issued  through   the
       handle,	and  any  other  resources  required  by  the  implementation.	SLP properties	are not  encapsulated
	by the handle, they  are global.  The return value  of	the  function  is  an  SLPError  code  indicating  the	status of  the	operation.
       Upon  failure,  the  phSLP parameter is NULL.

       An SLPHandle can only be used for one SLP API operation at a time. If the original operation was started  asynchronously,  any  attempt	to
       start  an  additional  operation  on the handle while the original operation is pending results in the return of an SLP_HANDLE_IN_USE error
       from the API function.  The SLPClose()  function terminates any outstanding calls on the handle.

PARAMETERS

       pcLang	       A pointer  to an  array of  characters containing  the  language tag set forth in RFC 1766 for the natural language  locale
		       of requests issued on the handle.  This parameter cannot be NULL.

       isAsync	       An SLPBoolean indicating whether or not the SLPHandle should be opened for an asynchronous operation.

       phSLP	       A pointer to an SLPHandle in which the open SLPHandle is returned. If an error occurs, the value upon return is NULL.

ERRORS

       This function or its callback may return any SLP error code. See the ERRORS section in slp_api(3SLP).

EXAMPLES

       Example 1: Using SLPOpen()

       Use the following example to open a synchronous handle for the German ("de") locale:

       SLPHandle HSLP; SLPError err;  err = SLPOpen("de", SLP_FALSE, &hSLP)

SLPFindScopes(3SLP)				    Service Location Protocol Library Functions 			       SLPFindScopes(3SLP)

NAME

       SLPFindScopes - return list of configured and discovered scopes

SYNOPSIS

       cc [ flag... ] file... -lslp [ library... ]
       #include <slp.h>

       SLPError SLPFindScopes(SLPHandle hSLP, char** ppcScopes);

DESCRIPTION

       The  SLPFindScopes()  function sets the ppcScopes parameter  to	a pointer to a comma-separated list including  all available scope  names.
       The list of  scopes comes from  a variety of  sources: the configuration file, the net.slp.useScopes property and  the  net.slp.DAAddresses
       property,    DHCP,    or   through  the	 DA discovery  process.  If  there is  any  order  to the  scopes,  preferred  scopes  are  listed
       before less  desirable  scopes.	There  is  always  at  least one  string in the  array, the  default  scope,  DEFAULT.

       If no error occurs, SLPFindScopes() returns SLP_OK, otherwise, it returns the appropriate error code.

PARAMETERS

       hSLP	    The SLPHandle on which to search for scopes.  hSLP cannot be NULL.

       ppcScopes    A  pointer to  a char  pointer  into  which  the  buffer pointer is placed upon return. The buffer is  null-terminated.    The
		    memory should be freed by calling SLPFree(). See SLPFree(3SLP)

ERRORS

       This function or its callback may return any SLP error code. See the ERRORS section in slp_api(3SLP).

EXAMPLES

       Example 1 Finding Configured or Discovered Scopes

       Use the following example to find configured or discovered scopes:

	 SLPHandle hSLP;
	 char *ppcScopes;
	 SLPError err;

	 error = SLPFindScopes(hSLP, & ppcScopes);

ENVIRONMENT VARIABLES

       SLP_CONF_FILE	When set, use this file for configuration.
