NAME

mongoc_gridfs_file_writev() - Performs a gathered write to the underlying gridfs file.

SYNOPSIS

ssize_t
mongoc_gridfs_file_writev (mongoc_gridfs_file_t *file,
                           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: A uint32_t with the timeout in milliseconds.

DESCRIPTION

Performs a gathered write to the underlying gridfs file.

If timeout is reached, then -1 is returned and errno is set to ETIMEDOUT.

RETURNS

Returns the number of bytes written or -1 upon error and errno is set.

mongoc_gridfs_file_readv (3) - This function performs a scattered read from file, potentially blocking to read from the MongoDB server.
mongoc_gridfs_file_remove (3) - Removes file and its data chunks from the MongoDB server.
mongoc_gridfs_file_save (3) - Saves modifications to file to the MongoDB server.
mongoc_gridfs_file_seek (3) - Adjust the file position pointer in the given file by delta, starting from the position whence. The whence argument is interpreted as in fseek(2):
mongoc_gridfs_file_set_aliases (3) - Sets the aliases for a gridfs file.
