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.

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

NAME

       SLPFindSrvs - return service URLs

SYNOPSIS

       #include <slp.h>

       SLPError  SLPFindSrvs(SLPHandle	hSLP,  const  char  *pcServiceType, const char *pcScopeList, const char *pcSearchFilter, SLPSrvURLCallback
       *callback, void *pvCookie);

DESCRIPTION

       The SLPFindSrvs() function issues a request for SLP services. The query is for services on a language-specific SLPHandle.  It  returns  the
       results through the callback. The parameters will determine the results.

       If an error occurs  in starting the operation, one  of  the SLPError codes is returned.

PARAMETERS

       hSLP		       The language-specific SLPHandle on which to  search for services. It cannot  be NULL.

       pcServiceType	       The  service  type string for the request. The pcServiceType can be discovered by a call to SLPSrvTypes(). Examples
			       of service type strings include

			       "service:printer:lpr"

			       or

			       "service:nfs"

			       pcServiceType cannot be NULL.

       pcScopeList	       A pointer to a char containing a comma-separated  list  of scope names. It cannot be NULL or an empty string, "".

       pcSearchFilter	       A query formulated of attribute pattern matching expressions in the form of a LDAPv3 search filter. See	RFC  2254.
			       If  this filter is empty, "", all services of the requested type in the specified scopes are returned. It cannot be
			       NULL.

       callback 	       A callback through which the results of the operation are reported. It cannot be NULL.

       pvCookie 		Memory passed to the callback code from the client. It can be 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 SLPFindSrvs()

       The following example finds all advertisements for printers supporting the LPR protocol with the dpi attribute 300 in the default scope:

       SLPError err;
       SLPHandle hSLP;
       SLPSrvURLCallback srvngst;

       err = SLPFindSrvs(hSLP,
			 "service:printer:lpr",
			 "default",
			 "(dpi=300)",
			 srvngst,
			 NULL);

ENVIRONMENT VARIABLES

       SLP_CONF_FILE	       When set, use this file for configuration.
