C語言[3] 文件IO

FILE *fopen(const char *filename, const char *mode)
int fclose( FILE *fp );
返回值：如果流成功關閉，fclose 返回 0，否則返回EOF.

int fgetc ( FILE * stream );
int fputc ( int character, FILE * stream );
int getc ( FILE * stream );
int putc ( int character, FILE * stream );
* 一樣

char * fgets ( char * str, int num, FILE * stream );
int fputs ( const char * str, FILE * stream );
char * gets ( char * str );
int puts ( const char * str );
* 兩個不同，fputs 指定了文件流， 且不會自動換行

size_t fread ( void * ptr,       size_t size, size_t count, FILE * stream );
size_t fwrite( const void * ptr, size_t size, size_t count, FILE * stream );

int getchar ( );
int putchar ( int character );

int fprintf ( FILE * stream, const char * format, ... );
int fscanf ( FILE * stream, const char * format, ... );

C語言提供了一些文件IO函數，有點糊塗了，還有標準IO，特此區分一下。
