Linux C fgetc(), fputc()

// fgetc_fputc.c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int 
main()
{
    FILE *fp0 = (FILE *)NULL, *fp1 = (FILE *)NULL;
    char cKey = '\0';

    fp0 = fopen("GET.TXT", "r");
    if (fp0 == NULL) {
        fclose(fp0);
        exit(EXIT_FAILURE);
    }

    fp1 = fopen("PUT.TXT", "w+");
    if (fp1 == NULL) {
        fclose(fp1);
        exit(EXIT_FAILURE);
    }

    while((cKey = fgetc(fp0)) != EOF)
        fputc(cKey, fp1);

    fclose(fp0);
    fclose(fp1);

    exit(EXIT_SUCCESS);
}

fgetc(), fputc()和fgets(), fputs()的差異在它是以字元 (sizeof(char))為單位，來對檔案做讀取寫入的動作，所以它就沒有換行字元 ('\n')的概念....

函式原型：

int fgetc(FILE *stream);

int fputc(int c, FILE *stream);
