Overview

get_next_line is a function that reads a single line from a file descriptor, returning the line read as a char *. It works with multiple file descriptors, allowing you to read from multiple files simultaneously.

This repository contains the source code for get_next_line, as well as a test suite and example programs that demonstrate its usage.

Usage

To use the get_next_line function, you need to include the header file in your C program and open the file that you want to read using the open function. Then, allocate memory for a char * to store the line read by get_next_line and call the function with the file descriptor and the address of the char *. Check the return value of get_next_line to determine the status: if it is not NULL, a line was read successfully; if it is NULL, the end of the file was reached; When you are finished with the char *, free the memory allocated for it 😜.

int fd;
char *line;

line = get_next_line(fd);

If no text to read is discovered, the get_next_line function returns NULL.

API

The get_next_line function has the following prototype:

int get_next_line(int fd, char **line);
