ExampleIntroductionStreams and FILE objectsBufferingOpening a StreamReading and writing a streamIf this is a serious issue, then we should modify our code to:#include int main(int argc, char *argv[]){FILE *f;char c;f=fopen(argv[1], "w");setbuf(f, NULL);while((c=getchar()) != EOF)fputc(c, f);}or to#include int main(int argc, char *argv[]){FILE *f;char c;f=fopen(argv[1], "w");while((c=getchar()) != EOF){fputc(c, f);fflush(f);}}Standard Input/Output Library60-256 System Programming
IntroductionStreams and FILE objectsBufferingOpening a StreamReading and writing a streamString/Line Input functionsInput functions:char *fgets(char *dest, int n, FILE *fp)Reads up through, including, the next newline, but no morethan n-1 characters. Then NULL added to whatever hasbeen read.char *gets(char *dest)Reads from stdin in a similar way as fgets(), but hassome serious side effects. In particular, it allows buffer tooverflow. It should never be used!Note that dest is the address of the array to read thecharacters into it. Both functions return dest if OK, NULLotherwise (end-of-file or error).Standard Input/Output Library60-256 System Programming
