.SH "NAME"
|
|
zmq_msg_more \- indicate if there are more message parts to receive
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
\fBint zmq_msg_more (zmq_msg_t \fR\fB\fI*message\fR\fR\fB);\fR
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fIzmq_msg_more()\fR function indicates whether this is part of a multi\-part message, and there are further parts to receive\&. This method can safely be called after \fIzmq_msg_close()\fR\&. This method is identical to \fIzmq_msg_get()\fR with an argument of ZMQ_MORE\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
The \fIzmq_msg_more()\fR function shall return zero if this is the final part of a multi\-part message, or the only part of a single\-part message\&. It shall return 1 if there are further parts to receive\&.
|
|
.SH "EXAMPLE"

|
\fBReceiving a multi-part message\fR.
