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