\title{Create message buffer}
\description{
Creates a new message buffer
}
\usage{
.PVM.mkbuf (encoding = c("Default", "Raw", "InPlace"))
}
\arguments{
\item{encoding}{a character string specifying the next message's
encoding scheme. Must be one of \code{"Default"} (default),
\code{"Raw"} or \code{"InPlace"}.}
}
\value{
Returns message buffer id or -1 if failed..
}
\details{
This function creates a new message buffer and sets its encoding theme
(see \code{\link{.PVM.initsend}}.
It is useful if the user wishes to manage multiple message buffers and
should be used in conjunction with \code{\link{.PVM.freebuf}}.
\code{\link{.PVM.freebuf}} should be called for a send buffer after a
message has been send and is no longer needed.
Receive buffer are created automatically by \code{\link{.PVM.recv}}
and \code{\link{.PVM.nrecv}} routines and do not have to be freed
unless they have been explicitly saved with \code{\link{.PVM.setrbuf}}.
Typically multiple send and receive buffer are not needed and the user
can simply use the \code{\link{.PVM.initsend}} to reset the default
send buffer.
