46 * about a file write. Examples include the file name, offset, length,
169 * control where the record will be written. If offset is < 0, the
171 * record which exists at the indicated offset will be overlayed. This
175 * offset is >= 0, only the fixed length portion of the record is

200 * If offset is -1, we append the record at the end of file
202 * Otherwise, we overlay wrec at the file offset indicated and assume
203 * that the caller passed us the correct offset. We do not record the
