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.
