NAME
nng_iov - scatter/gather element
SYNOPSIS
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.
