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
           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.
