SLPFINDSCOPES(3SLP) Service Location Protocol Library Functions
SLPFindScopes - return list of configured and discovered scopes
cc [ flag... ] file... -lslp [ library... ]
#include <slp.h>
SLPError SLPFindScopes(SLPHandle hSLP, char** ppcScopes);
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.
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)
This function or its callback may return any SLP error code. See the
ERRORS section in slp_api(3SLP).
Use the following example to find configured or discovered scopes:
SLPHandle hSLP;
char *ppcScopes;
SLPError err;
error = SLPFindScopes(hSLP, & ppcScopes);
SLP_CONF_FILE
When set, use this file for configuration.

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

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.
