** Функция write имеет следующие параметры (<дескриптор.потока>, <&указатель на буфер>, <число.записыв.байтов>):
**
** 1. int <дескриптор(идентификатор) потока ввода/вывода>:
** 0 stdin – стандартное устройство ввода (клавиатура);
** 1 stdout – стандартное устройство вывода (экран);
** 2 stderr – стандартное устройство вывода сообщения об ошибках (также экран).
** Простыми словами при открытии файла операционная система создает запись для представления этого файла
** и сохраняет информацию об этом открывшемся файле. Итак, если в вашей ОС открыто 100 файлов, то в ОС
** будет находиться 100 записей (где-то в ядре). Эти записи представлены целыми числами типа (... 100, 101, 102....).
** Этот номер записи является файловым дескриптором. Таким образом, это просто целое число, которое уникально
** представляет собой открытый файл в операционной системе. Если ваш процесс откроет 10 файлов, ваша таблица процессов
** будет содержать 10 записей для дескрипторов файлов.
** Еще простыми словами: чтобы попасть в город (прочитать/записать в файл) мы едем через мост (дескриптор).
**
** 2. const void *buf <указатель на буфер> - адрес, куда мы будем записывать наши данные (байты) и возращать их.
** Значение из ft_putchar(char c(отсюда)) передав его в write(1, &c(cюда), 1).
** Синтаксис, когда мы делаем ссылку на адрес с → &c.

** 3. size_t count <число записываемых байтов> - количество пересылаемых данных (1 byte - 1 char).
** Эта функция записывает один символ в стандартный поток вывода терминала.

* fflush（更新缓冲区）
* 相关函数 write，fopen，fclose，setbuf
* 表头文件 #include<stdio.h>

* fseek（移动文件流的读写位置）
* 相关函数 rewind，ftell，fgetpos，fsetpos，lseek
* 表头文件 #include<stdio.h>
* 定义函数 int fseek(FILE * stream,long offset,int whence);
* 函数说明 fseek()用来移动文件流的读写位置。参数stream为已打开的文件指针，参数offset为根据参数whence来移动读写位置的位移数。
* 参数 whence为下列其中一种:
* SEEK_SET从距文件开头offset位移量为新的读写位置。SEEK_CUR 以目前的读写位置往后增加offset个位移量。
* SEEK_END将读写位置指向文件尾后再增加offset个位移量。
* 当whence值为SEEK_CUR 或SEEK_END时，参数offset允许负值的出现。
* 下列是较特别的使用方式:
* 1) 欲将读写位置移动到文件开头时:fseek(FILE *stream,0,SEEK_SET);
* 2) 欲将读写位置移动到文件尾时:fseek(FILE *stream,0,0SEEK_END);
* 返回值 当调用成功时则返回0，若有错误则返回-1，errno会存放错误代码。
* 附加说明 fseek()不像lseek()会返回读写位置，因此必须使用ftell()来取得目前读写的位置。

******************************************************************************
**
** This file contains the implementation of an SQLite virtual table for
** reading CSV files.
**
** Usage:
**
** .load ./csv
** CREATE VIRTUAL TABLE temp.csv USING csv(filename=FILENAME);
** SELECT * FROM csv;
**
** The columns are named "c1", "c2", "c3", ... by default. Or the
** application can define its own CREATE TABLE statement using the
** schema= parameter, like this:
**
** CREATE VIRTUAL TABLE temp.csv2 USING csv(
** filename = "../http.log",
** schema = "CREATE TABLE x(date,ipaddr,url,referrer,userAgent)"
** );
**
** Instead of specifying a file, the text of the CSV can be loaded using
** the data= parameter.
**
** If the columns=N parameter is supplied, then the CSV file is assumed to have
** N columns. If both the columns= and schema= parameters are omitted, then
** the number and names of the columns is determined by the first line of
** the CSV input.
**
** Some extra debugging features (used for testing virtual tables) are available
** if this module is compiled with -DSQLITE_TEST.

must conform to the following style:
int Funct(arg1, arg2, ...) {
/* brief description of how your implementation works */
int var1 = Expr1;
...
int varM = ExprM;
varJ = ExprJ;
...
varN = ExprN;
return ExprR;
}
Each "Expr" is an expression using ONLY the following:
1. Integer constants 0 through 255 (0xFF), inclusive. You are
not allowed to use big constants such as 0xffffffff.
2. Function arguments and local variables (no global variables).
3. Unary integer operations ! ~
4. Binary integer operations & ^ | + << >>
Some of the problems restrict the set of allowed operators even further.
Each "Expr" may consist of multiple operators. You are not restricted to
one operator per line.
You are expressly forbidden to:
1. Use any control constructs such as if, do, while, for, switch, etc.
2. Define or use any macros.
3. Define any additional functions in this file.
4. Call any functions.
5. Use any other operations, such as &&, ||, -, or ?:
6. Use any form of casting.
7. Use any data type other than int. This implies that you
cannot use arrays, structs, or unions.
You may assume that your machine:
1. Uses 2s complement, 32-bit representations of integers.
2. Performs right shifts arithmetically.
3. Has unpredictable behavior when shifting an integer by more
than the word size.
EXAMPLES OF ACCEPTABLE CODING STYLE:
/*
* pow2plus1 - returns 2^x + 1, where 0 <= x <= 31
*/
int pow2plus1(int x) {
/* exploit ability of shifts to compute powers of 2 */
return (1 << x) + 1;
}
/*
* pow2plus4 - returns 2^x + 4, where 0 <= x <= 31
*/
int pow2plus4(int x) {
/* exploit ability of shifts to compute powers of 2 */
int result = (1 << x);
result += 4;
return result;
}
FLOATING POINT CODING RULES
For the problems that require you to implent floating-point operations,
the coding rules are less strict. You are allowed to use looping and
conditional control. You are allowed to use both ints and unsigneds.
You can use arbitrary integer and unsigned constants.
You are expressly forbidden to:
1. Define or use any macros.
2. Define any additional functions in this file.
3. Call any functions.
4. Use any form of casting.
5. Use any data type other than int or unsigned. This means that you
cannot use arrays, structs, or unions.
6. Use any floating point data types, operations, or constants.
NOTES:
1. Use the dlc (data lab checker) compiler (described in the handout) to
check the legality of your solutions.
2. Each function has a maximum number of operators (! ~ & ^ | + << >>)
that you are allowed to use for your implementation of the function.
The max operator count is checked by dlc. Note that '=' is not
counted; you may use as many of these as you want without penalty.
3. Use the btest test harness to check your functions for correctness.
4. Use the BDD checker to formally verify your functions
5. The maximum number of ops for each function is given in the
header comment for each function. If there are any inconsistencies
between the maximum ops in the writeup and in this file, consider
this file the authoritative source.
/*
* STEP 2: Modify the following functions according the coding rules.
*
* IMPORTANT. TO AVOID GRADING SURPRISES:
* 1. Use the dlc compiler to check that your solutions conform
* to the coding rules.
* 2. Use the BDD checker to formally verify that your solutions produce
* the correct answers.
