.SH NAME
SLPFindScopes \- return list of configured and discovered scopes
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR... ] \fIfile\fR... \fB-lslp\fR [ \fIlibrary\fR... ]
#include <slp.h>

\fBSLPError\fR \fBSLPFindScopes\fR(\fBSLPHandle\fR \fIhSLP\fR, \fBchar**\fR \fIppcScopes\fR);

.SH DESCRIPTION
.sp
.LP
The \fBSLPFindScopes()\fR function sets the \fIppcScopes\fR 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 \fBnet.slp.useScopes\fR property and the \fBnet.slp.DAAddresses\fR  property,   \fBDHCP\fR,   or  through the  \fBDA\fR 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,  \fBDEFAULT\fR.
.sp
.LP
If no error occurs, \fBSLPFindScopes()\fR returns \fBSLP_OK\fR, otherwise, it returns the appropriate error code.
