Synopsis

int
mongoc_gridfs_file_seek (mongoc_gridfs_file_t *file, int64_t delta, int whence);

Parameters

SEEK_CURMove delta relative to the current file position.
SEEK_ENDMove delta relative to the end of the file.

On success, the file's underlying position pointer is set appropriately. On failure, the file position is NOT changed and errno is set to indicate the error.
