我不清楚发送响应时服务器的规则是什么：
array = NULL;
struct record record;
while (fscanf(inFile, "%d:%d:%d:%d:%99[^\n]", &record.src, &record.dest
, &record.type, &record.port
, record.data) == 5) {
/* It's possible that a user might enter more than *
* 99 chars for the last field, so when that happens *
* we should discard the remainder... */
if (getchar() != '\n') {
puts("WARNING: Maximum field length for data is 99; user input truncated");
fscanf(inFile, "%*[^\n]");
}
void *temp = realloc(array, (count + 1) * sizeof *array);
if (!temp) {
puts("ERROR ALLOCATING MEMORY!");
exit(EXIT_FAILURE);
}
array = temp;
array[count++] = record;
}
标头？在什么情况下？
