SLPFINDSCOPES(3SLP) Service Location Protocol Library Functions

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).
