.SH DESCRIPTION
.sp
.LP
The \fBSLPReg()\fR function registers the  \fBURL\fR  in \fIpcSrvURL\fR  having
the  lifetime  \fIusLifetime\fR with  the attribute  list in  \fIpcAttrs\fR.
The  \fIpcAttrs\fR list is  a comma-separated list of  attribute  assignments
in on-the-wire format (including  escaping  of  reserved  characters).   The
\fIsLifetime\fR  parameter  must  be  nonzero  and less than or equal to
\fBSLP_LIFETIME_MAXIMUM\fR. If the fresh  flag is  \fBSLP_TRUE\fR, then the
registration is  new, the \fBSLP\fR protocol  \fIfresh\fR  flag is set, and the
registration replaces any existing registrations.
.sp
.LP
The \fIpcSrvType\fR parameter is a service type name and can be included for
service \fBURL\fRs that are not in the service:  scheme.  If the \fBURL\fR is
in the service:  scheme, the \fIpcSrvType\fR parameter is ignored.  If the
fresh flag is \fBSLP_FALSE\fR, then an existing registration is updated. Rules
for new and updated registrations, and the format for \fIpcAttrs\fR and
\fIpcScopeList\fR, can be found in \fIRFC 2608\fR. Registrations and updates
take place in the language locale of the \fIhSLP\fR handle.
.sp
.LP
The \fBAPI\fR library is required to perform the operation in all scopes
obtained through configuration.
