 SLPFINDSCOPES 3SLP "Jan 16, 2003"
 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.
