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