A C function that reads any valid file line by line - @42sp Project

A library of useful C functions

Pipex is a project commonly assigned in the curriculum of the 42 coding school. Its main objective is to introduce students to UNIX pipes and inter-process communication. In Pipex, you re-create in C the shell's pipeline operator (`|`), which allows the output of one command to be used as the input for another command.

get_next_line (GNL): project focused on file I/O and memory management. The task is to write a single function, get_next_line, that reads from a file descriptor and returns one line at a time. This project requires careful handling of static variables, buffer management, and reading data in chunks to efficiently process files of any size.

42 Cursus Projects

create nonlinear pipelines with file descriptors

the idea of the project is that u need to create a function that reads one line from a file descriptor each time u call it until it reaches the EOF using static vars so u can preserve their previous value and start from where u finished in the next call.

This function reads from a file descriptor and returns a single line at a time. It’s designed to handle any file or standard input efficiently, making it easy to process text line by line.

42cursus-Pipex: C program that recreates the functionality of shell pipes (|) and HereDoc (<< Del). This project focuses on inter-process communication by using fork(), pipe(), dup2(), and execve() to redirect the output of one command to the input of another, mimicking the shell command < infile cmd1 | cmd2 > outfile.

The aim of this project is to make you code a function that returns a line ending with a newline, read from a file descriptor.

Function to read lines from a file descriptor one-by-one using static variables.
