NAME
mongoc_stream_readv()

SYNOPSIS
ssize_t
mongoc_stream_readv (mongoc_stream_t *stream,
                     mongoc_iovec_t  *iov,
                     size_t           iovcnt,
                     size_t           min_bytes,
                     int32_t          timeout_msec);

PARAMETERS

stream
    A mongoc_stream_t .

iov A vector of mongoc_iovec_t .

iovcnt
    The number of items in iov .

min_bytes
    The minimum number of bytes to read or failure will be indicated.

timeout_msec
    A timeout in milliseconds, or 0 to indicate non-blocking. A negative value with use the default timeout.

This function is identical to mongoc_stream_read(3) except that it takes a mongoc_iovec_t to perform gathered I/O.

RETURNS
>= 0 on success, -1 on failure and errno is set.
