NAME

       SLPOpen - open an SLP handle

SYNOPSIS

       cc [ flag... ] file... -lslp [ library... ]
       #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)

ENVIRONMENT VARIABLES

       SLP_CONF_FILE	When set, use this file for configuration.
