.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);
.fi

.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.
.SH PARAMETERS
.sp
.ne 2
.mk
.na
\fB\fIhSLP\fR\fR

The \fBSLPHandle\fR on which to search for scopes.  \fIhSLP\fR cannot be
\fINULL\fR.

.RS 13n
.rt  
A  pointer to  a \fBchar\fR  pointer  into  which  the  buffer pointer is
placed upon return. The buffer is null-terminated.   The memory should be freed
by calling \fBSLPFree()\fR. See \fBSLPFree\fR(3SLP)

.SH ERRORS
.sp
.LP
This function or its callback may return any \fBSLP\fR error code. See the
ERRORS section in \fBslp_api\fR(3SLP).
.SH EXAMPLES

.nf
SLPHandle hSLP;
char *ppcScopes;
SLPError err;

error = SLPFindScopes(hSLP, & ppcScopes);
.fi
.in -2
