mongoc_gridfs_file_writev − mongoc_gridfs_file_writev()
ssize_t mongoc_gridfs_file_writev (mongoc_gridfs_file_t *file, const mongoc_iovec_t *iov, size_t iovcnt, uint32_t timeout_msec);
• |
file: A mongoc_gridfs_file_t. |
|||
• |
iov: An array of mongoc_iovec_t. |
|||
• |
iovcnt: The number of elements in iov. |
|||
• |
timeout_msec: Unused. |
Performs a gathered write to the underlying gridfs file.
The timeout_msec parameter is unused.
Modifying GridFS files is NOT thread−safe. Only one thread or process can access a GridFS file while it is being modified.
Returns the number of bytes written, or −1 on failure. Use mongoc_gridfs_file_error() to retrieve error details.
