.SH NAME
SLPParseSrvURL \- parse service URL
.SH SYNOPSIS
.LP
.nf
cc [ \fIflag\fR... ] \fIfile\fR... \fB-lslp\fR [ \fIlibrary\fR... ]
#include <slp.h>

\fBSLPError\fR \fBSLPParseSrvURL\fR(\fBconst char *\fR\fIpcSrvURL\fR, \fBSLPSrvURL**\fR \fIppSrvURL\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBSLPParseSrvURL()\fR routine parses  the \fBURL\fR passed in as the
argument into a service \fBURL\fR structure  and returns it  in the
\fIppSrvURL\fR  pointer.    If a parser error occurs,   returns
\fBSLP_PARSE_ERROR\fR. The  structure  returned  in  \fIppSrvURL\fR should  be
freed with  \fBSLPFree()\fR.  If  the \fBURL\fR has  no service  part, the
\fBs_pcSrvPart\fR string  is  the empty string, \fB""\fR,  that is, it is not
\fINULL\fR. If \fIpcSrvURL\fR  is  not a  service:  URL,  then the
\fBs_pcSrvType\fR field  in  the  returned data  structure  is  the
\fBURL\fR's  scheme,  which might not be the same as the service type  under
which the  \fBURL\fR was  registered.  If  the transport  is  \fBIP\fR, the
\fBs_pcNetFamily\fR field is the empty string.
.sp
.LP
If no error  occurs, the return  value is the  \fBSLP_OK\fR.  Otherwise, if  an
error  occurs, one  of the  \fBSLPError\fR  codes  is returned.
.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIpcSrvURL\fR\fR
.ad
.RS 12n
A pointer to  a character buffer  containing the  null  terminated URL string
to parse.  It is destructively modified to produce the output structure. It may
not be \fINULL\fR.

\fB\fIppSrvURL\fR\fR
.ad
.RS 12n
 A pointer to a  ponter for the \fBSLPSrvURL\fR structure  to  receive the
parsed \fBURL\fR. It may not be \fINULL\fR.

.SH ERRORS
.sp

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