SYNOPSIS

ssize_t
mongoc_gridfs_file_writev (mongoc_gridfs_file_t *file,


                           const mongoc_iovec_t *iov,


                           size_t iovcnt,


                           uint32_t timeout_msec);

PARAMETERS

file: A mongoc_gridfs_file_t.
iov: An array of mongoc_iovec_t.
iovcnt: The number of elements in iov.
timeout_msec: Unused.

DESCRIPTION

Performs a gathered write to the underlying gridfs file.

The timeout_msec parameter is unused.
