That's odd. It is supposed to write "bufpos" bytes, the first 4 (or 8 on
64-bit) are the exact values of the pointer (p.bufptr) you want to write.

In the case you want to write the content the pointer points TO, try

pchar(f.bufptr)[0]  or f.bufptr^ if that is allowed (I don't know what
bufptr exactly is)
