This is my own implementation of getline() from C library
Getting the next line is an ungly job in C, luckily there is getline() from the standard input/output library. I have created my own program to mimic the behavior of getline(), and to gain a better understanding of file descriptors in Linux operating system.
| Function name | get_next_line |
|---|---|
| Prototype | char *get_next_line(int fd); |
| Turn in files | get_next_line.c, get_next_line_utils.c, get_next_line.h |
| Parameters | fd: The file descriptor to read from |
| Return value | Read line: correct behavior NULL: there is nothing else to read, or an error occurred |
| External functs | read, malloc, free |
| Description | A function that returns a line read from a file descriptor |
Basically get_next_line(fd) keeps reading form the provided file descriptor until
it encounters new line character \n then return it as a string, it also keeps
track of the file if you try to use it again it would get you the next available line "DA ;)"
If you use the bonus files instead of the main files you gain the functionality of using different
file descriptors after each other while get_next_line(fd) keeps track of each one of them, so you
you can go back and continue reading any of them from the stop point from the last call of
get_next_line(fd)
If you have any optimization idea about the code please let me know :)
