NAME¶
mongoc_stream_readv - 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() except that it takes a mongoc_iovec_t to perform gathered I/O.
