NAME¶

nng_iov - scatter/gather element

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

iov_len
