gets, fgets - get a string from a stream
Syntax
#include <stdio.h>
char *gets(s)
char *s;
char *fgets(s, n, stream)
char *s;
int n;
FILE *stream;
Description
The routine reads a string into s from the standard input stream stdin. The string is terminated by a newline character, which is replaced
in s by a null character. The routine returns its argument.
The routine reads n-1 characters, or up to a newline character, whichever comes first, from the stream into the string s. The last charac-
ter read into s is followed by a null character. The routine returns its first argument.
Restrictions
The routine deletes a newline, while keeps it.
Diagnostics
The and routines return the constant pointer NULL upon end of file or error.

gets, fgets - get a string from a stream
SYNOPSIS
#include <stdio.h>
char *gets(char *s);
char *fgets(char *s, int n, FILE *stream);
DESCRIPTION
The gets() function reads bytes from the standard input stream (see Intro(3)), stdin, into the array pointed to by s, until a newline char-
acter is read or an end-of-file condition is encountered. The newline character is discarded and the string is terminated with a null byte.
If the length of an input line exceeds the size of s, indeterminate behavior may result. For this reason, it is strongly recommended that
gets() be avoided in favor of fgets().
The fgets() function reads bytes from the stream into the array pointed to by s, until n-1 bytes are read, or a newline character is read
and transferred to s, or an end-of-file condition is encountered. The string is then terminated with a null byte.
The fgets() and gets() functions may mark the st_atime field of the file associated with stream for update. The st_atime field will be
marked for update by the first successful execution of fgetc(3C), fgets(), fread(3C), fscanf(3C), getc(3C), getchar(3C), gets(), or
scanf(3C) using stream that returns data not supplied by a prior call to ungetc(3C) or ungetwc(3C).
RETURN VALUES
If end-of-file is encountered and no bytes have been read, no bytes are transferred to s and a null pointer is returned. For standard-con-
forming (see standards(5)) applications, if the end-of-file indicator for the stream is set, no bytes are transferred to s and a null
pointer is returned whether or not the stream is at end-of-file. If a read error occurs, such as trying to use these functions on a file
that has not been opened for reading, a null pointer is returned and the error indicator for the stream is set. If end-of-file is encoun-
tered, the EOF indicator for the stream is set. Otherwise s is returned.
ERRORS
Refer to fgetc(3C).

Hi all,
I have this method to read a string from a STDIN:
void readLine(char* inputBuffer){
fgets (inputBuffer, MAX_LINE, stdin);
fflush(stdin);
/* remove '\n' char from string */
if(strlen(inputBuffer) != 0)
inputBuffer = '\0';
}
All work fine but if i... (1 Reply)
I've been having trouble with reading past the end-of-file in C. Can anyone find my stupid mistake?
This is the minimal code needed to cause the error for me:
FILE *f = fopen(name, "r");

hello,
i'm trying to write a C-program that reads a file line by line.
(and searches each line for a given string)
This file is an special ASCII-database-file, with a lot of entries.
I checked the line with most length, and it was about 4000 characters.
With google i found several... (4 Replies)
Hi,
I have a string like this,
char str ="This, a sample string.\\nThis is the second line, \\n \\n, we will have one blank line";
if I want to use strtok() to seperate the string, which token should I use?
I tried "\n", "\\n", either not working.

I was wondering what is the correct way to read in data "one-part-per-line" as compared with "one-record-per-line" formats into the same structure in C?
