  • 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() except that it takes a mongoc_iovec_t to perform gathered I/O.

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