How to write non-text data to SD via tinyFAT library

Does anyone know how to write a byte of data to SD using the henningkarlsen tinyFAT library? The examples with the library show how to read and write text, and also how to read a word but not how to write a word (or more specifically, a byte). Within the library itself there is even a "file.readBinary();" command, but there is no such "file.writeBinary" command.

I believe it's probably done through the buffer, but does anyone know how?

thank you

I have a same problem. Write no-text or no literal using tinyfat. i would like write variables

tinyFAT does not support writing binary data…
