SYNOPSIS

+
+
+
+
#include <nng/nng.h>
+
+typedef struct {
+    void * iov_buf;
+    size_t iov_len;
+} nng_iov;
+
+
+
+
+
+

DESCRIPTION

+
+
+

An nng_iov structure represents a single element in a scatter/gather +array. +Some operations can use arrays of these to access different regions of +memory in a single operation. +For example, it may be useful to send a message with header data from +one part of memory, and a user payload from another.

+
+
+

The operations that do this typically store an array of these in +an nng_aio structure using the +nng_aio_set_iov() function.

+
+
+

The following structure members are present:

+
+
+
+
iov_buf
+
+

This is a pointer to the first byte within the memory being +referenced by this scatter/gather element.

+
+
iov_len
+
+

This is the size in bytes of this scatter/gather element.

+
+
+
+
+
+
