FWrite -- Writes a number of blocks to an output (buffered) (V36)
count = FWrite(fh, buf, blocklen, blocks)
D0 D1 D2 D3 D4
LONG FWrite(BPTR, STRPTR, ULONG, ULONG)
Attempts to write a number of blocks, each blocklen long, from the
specified buffer to the output stream. May return less than the
number of blocks requested, if there is some error such as a full
disk or r/w error. This call is buffered.
fh - filehandle to use for buffered I/O
buf - Area to write bytes from.
blocklen - number of bytes per block. Must be > 0.
blocks - number of blocks to write. Must be > 0.
count - Number of _blocks_ written. On an error, the number of
blocks actually written is returned.
Doesn't clear IoErr() before starting. If you want to find out
about errors, use SetIoErr(0L) before calling.
