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?

explain_fgets_or_die
explain_fgets_or_die(3) Library Functions Manual explain_fgets_or_die(3)
NAME
explain_fgets_or_die - input of strings and report errors
SYNOPSIS
#include <libexplain/fgets.h>
char *explain_fgets_or_die(char *data, int data_size, FILE *fp);
DESCRIPTION
The explain_fgets_or_die function is used to call the fgets(3) system call. On failure an explanation will be printed to stderr, obtained
from explain_fgets(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
explain_fgets_or_die(data, data_size, fp);
data The data, exactly as to be passed to the fgets(3) system call.
data_size
The data_size, exactly as to be passed to the fgets(3) system call.
fp The fp, exactly as to be passed to the fgets(3) system call.
Returns:
This function only returns on success; data when a line is read, or NULL on end-of-file. On failure, prints an explanation and
exits.
