The ANSI C Standard, section 7.9.5.3, says:
Opening a file with append mode ('a' as the first character in the mode
argument) causes all subsequent writes to the file to be forced to the then
current end-of-file, regardless of intervening calls to the fseek function.
I don't know how to do what you want to do with ANSI C.
