.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\s-1EPP\s0 is the Extensible Provisioning Protocol. \s-1EPP\s0 (defined in \s-1RFC\s0 4930)
is an application layer client-server protocol for the provisioning and
management of objects stored in a shared central repository. Specified
in \s-1XML\s0, the protocol defines generic object management operations and an
extensible framework that maps protocol operations to objects. As of
writing, its only well-developed application is the provisioning of
Internet domain names, hosts, and related contact details.
.PP
This module implements functions that are common to both \s-1EPP\s0 clients and
servers that implement the \s-1TCP\s0 transport as defined in \s-1RFC\s0 4934. The
main consumer of this module is currently Net::EPP::Client.
.SH "METHODS"
.IX Header "METHODS"
.Vb 1
\& my $xml = Net::EPP::Protocol\->get_frame($socket);
.Ve
.PP
This method reads a frame from the socket and returns a scalar
containing the \s-1XML\s0. \f(CW$socket\fR must be an IO::Handle or one of its
subclasses (ie \f(CW\*(C`IO::Socket::*\*(C'\fR).
.PP
If the transmission fails for whatever reason, this method will
\&\f(CW\*(C`croak()\*(C'\fR, so be sure to enclose it in an \f(CW\*(C`eval()\*(C'\fR.
.PP
.Vb 1
\& Net::EPP::Protocol\->send_frame($socket, $xml);
.Ve
.PP
This method prepares an \s-1RFC\s0 4934 compliant \s-1EPP\s0 frame and transmits it to
the remote peer. \f(CW$socket\fR must be an IO::Handle or one of its
subclasses (ie \f(CW\*(C`IO::Socket::*\*(C'\fR).
.PP
If the transmission fails for whatever reason, this method will
\&\f(CW\*(C`croak()\*(C'\fR, so be sure to enclose it in an \f(CW\*(C`eval()\*(C'\fR. Otherwise, it will
return a true value.
.PP
.Vb 1
\& my $frame = Net::EPP::Protocol\->prep_frame($xml);
.Ve
.PP
This method returns the \s-1XML\s0 frame in \*(L"wire format\*(R" with the protocol
header prepended to it. The return value can be printed directly to an
open socket, for example:
.PP
.Vb 1
\& print STDOUT Net::EPP::Protocol\->prep_frame($frame\->toString);
