.TH SLPFINDSCOPES 3SLP "Jan 16, 2003"
.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
.na
\fB\fIhSLP\fR\fR
.ad
.RS 13n
The \fBSLPHandle\fR on which to search for scopes. \fIhSLP\fR cannot be
\fINULL\fR.
.RE
.sp
.ne 2
.na
\fB\fIppcScopes\fR\fR
.ad
.RS 13n
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)
.RE
.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
.LP
\fBExample 1 \fRFinding Configured or Discovered Scopes
.sp
.LP
Use the following example to find configured or discovered scopes:
.sp
.in +2
.nf
SLPHandle hSLP;
char *ppcScopes;
SLPError err;
error = SLPFindScopes(hSLP, & ppcScopes);
.fi
.in -2
.SH ENVIRONMENT VARIABLES
.sp
.ne 2
.na
\fB\fBSLP_CONF_FILE\fR\fR
.ad
.RS 17n
When set, use this file for configuration.
